Buyer-side trust oracle + capped sessions for x402 agents: verified_route, receipts, 17 free tools.
Scored across 25 tools
Several clusters overlap: token_price/token_market_data/market_snapshot, funding_rates/funding_spread/pre_trade_check, and route/verified_route/verified_route_preview. The detailed 'Not for' notes help, but the free preview versus paid oracle and the legacy route alias still invite misselection.
Names are consistently lowercase snake_case and mostly resource-oriented, with only minor verb-style deviations such as estimate_plan, web_search, and route. The legacy alias 'route' sitting next to verified_route is the main naming inconsistency.
At 25 tools, the surface is heavy for a server whose stated purpose is trust routing and spend caps, with much of it devoted to generic crypto data. Each tool is individually plausible, but the breadth dilutes focus and raises selection cost.
Routing and budgeting are partially covered by verified_route, verified_route_preview, estimate_plan, and session_create, but session lifecycle is create-only—there is no get, close, update, or remaining-spend check. The crypto data surface is broad, yet the spend-cap workflow has notable dead ends.
Latest crypto news and community sentiment from r/CryptoCurrency for any token
Use when: You need recent news headlines or community sentiment for one or more crypto tokens. Not for: you need general web news or documentation — web_search; a specific article's text — url_reader; a numeric sentiment gauge — fear_greed_index. Returns: headlines[] with title, url, sentiment (bullish/neutral/bearish), score, published_at Example response: {"currencies":"ETH","headlines":[{"title":"Ethereum devs confirm Pectra upgrade timeline","url":"https://reddit.com/r/CryptoCurrency/...","sentiment":"bullish","score":1842,"published_at":"2026-03-22T08:14:00Z"},{"title":"ETH gas fees drop to yearly lows","url":"https://reddit.com/r/CryptoCurrency/...","sentiment":"bullish","score":934,"published_at":"2026-03-22T06:31:00Z"}],"source":"reddit"}
Price: $0.000 USDC per call
Inputs: filter, currencies.
DeFi protocol Total Value Locked from DeFiLlama. Returns top 10 or a specific protocol.
Use when: You need the Total Value Locked in a specific DeFi protocol or want to compare the top protocols by TVL. Not for: you want the best yield for a token — yield_scanner; protocol revenue or custom metrics — dune_query. Returns: tvl, change_1h, change_1d, change_7d, chains[], category for the protocol (or top 10 list) Example response: {"protocol":"aave","tvl":23800000000,"change_1h":0.12,"change_1d":-1.43,"change_7d":3.21,"chains":["Ethereum","Polygon","Avalanche","Base"],"category":"Lending","source":"defillama"}
Price: $0.000 USDC per call
Inputs: protocol.
Run any Dune Analytics query and return live onchain results by query ID. Use fast_only=True for live bots — returns cached result instantly or raises immediately, never blocks.
Use when: You need deep onchain analytics from a specific Dune query — protocol revenue, user counts, custom metrics. Not for: you have no Dune query ID — the other tools cover prices, derivatives, TVL and security without one; you need sub-second answers — set fast_only=true or use a cached tool. Returns: rows[], columns[], row_count, generated_at from the Dune Analytics query result Example response: {"query_id":3810512,"row_count":2,"columns":["protocol","revenue_usd"],"rows":[{"protocol":"Uniswap V3","revenue_usd":1243800},{"protocol":"Aave V3","revenue_usd":987200}],"generated_at":"2026-03-22T00:00:00Z","source":"dune"}

Price a multi-tool plan BEFORE spending anything. Submits the tool calls an agent intends to make to the gateway's free /v1/plan/estimate and returns per-step cost, total, a fits-budget verdict, and a cheaper alternative per paid step. No payment, no wallet needed. Use when: planning a multi-step task with paid tools, "what would this cost", "does this plan fit my budget", or before committing a Session cap.
Inputs: steps (required), budget.
Crypto Fear & Greed Index (0=extreme fear, 100=extreme greed) with optional history
Use when: You need to gauge overall crypto market sentiment or mood — whether the market is fearful or greedy. Not for: you want token-specific sentiment — crypto_news (per-token headlines) or funding_rates (leveraged positioning). Returns: value (0–100), value_classification (e.g. 'Greed'), optional history[] Example response: {"value":10,"value_classification":"Extreme Fear","timestamp":1774137600,"source":"alternative.me"}
Price: $0.000 USDC per call
Inputs: limit.
Get perpetual futures funding rates across Binance, Bybit, and OKX
Use when: You need funding rates to gauge leveraged market sentiment or cost of holding a perp position. Not for: you need open interest or long/short ratio — open_interest; one verdict combining funding, OI, slippage and security for a trade — pre_trade_check. Returns: funding_rate_pct, annualized_rate_pct, sentiment (bullish/neutral/bearish) per exchange Example response: {"asset":"BTC","rates":[{"exchange":"binance","funding_rate_pct":0.012,"annualized_rate_pct":13.14,"sentiment":"bullish"},{"exchange":"bybit","funding_rate_pct":0.011,"annualized_rate_pct":12.04,"sentiment":"bullish"},{"exchange":"okx","funding_rate_pct":0.009,"annualized_rate_pct":9.85,"sentiment":"neutral"}],"source":"binance/bybit/okx"}
Price: $0.000 USDC per call
Inputs: asset.
Cross-venue perp funding divergence for one asset — the basis/carry read, not the raw rates. Reads Binance, Bybit, OKX, Gate.io, Bitget, Hyperliquid, dYdX, MEXC and KuCoin in parallel, normalises every rate to a per-8h figure (hourly venues scaled), and returns the spread (max minus min, cheapest and dearest venue, deviation from the median), its percentile against the last 7 days of cross-venue spreads, a plain-English read, and — given notional_usd — a carry estimate (per 8h / day / 30d) net of an assumed taker fee with the breakeven holding time. Venues that fail to answer are named in venues_unavailable; the spread is computed over the ones that did.
Use when: An agent wants to know whether funding on one venue is out of line with the others for the same perp — to pick the cheaper venue for a position, or to size a long/short carry across venues. Not for: you only need one venue's current funding — funding_rates is free; you want a trade verdict for one venue — pre_trade_check. This call settles $0.01 on-chain. Returns: asset, as_of, venues[{venue, rate_8h_pct, rate_annualized_pct, raw_rate_pct, interval_hours, next_funding_time}] sorted cheapest first, spread{pct_8h, bps_8h, annualized_pct, median_8h_pct, max_deviation_from_median_pct, cheapest, dearest}, history{days, buckets, spread_pct_8h_p50/p90/max, current_percentile}, carry_estimate{per_8h_usd, per_day_usd, per_30d_usd, taker_fees_round_trip_usd, breakeven_hours, assumptions} | null, read, venues_unavailable{venue: reason} Example response: {"asset":"ETH","as_of":"2026-11-05T12:41:00+00:00","venues":[{"venue":"okx","rate_8h_pct":0.01,"rate_annualized_pct":10.95,"raw_rate_pct":0.01,"interval_hours":8,"next_funding_time":1793923200000},{"venue":"hyperliquid","rate_8h_pct":0.01,"rate_annualized_pct":10.95,"raw_rate_pct":0.00125,"interval_hours":1,"next_funding_time":1793883600000},{"venue":"dydx","rate_8h_pct":0.039,"rate_annualized_pct":42.7,"raw_rate_pct":0.004875,"interval_hours":1,"next_funding_time":1793883600000}],"spread":{"pct_8h":0.029,"bps_8h":2.9,"annualized_pct":31.75,"median_8h_pct":0.01,"max_deviation_from_median_pct":0.029,"cheapest":"okx","dearest":"dydx"},"history":{"days":7,"buckets":22,"venues_with_history":["dydx","hyperliquid","okx"],"spread_pct_8h_p50":0.0125,"spread_pct_8h_p90":0.04242,"spread_pct_8h_max":0.05698,"current_percentile":77},"carry_estimate":{"notional_usd":10000,"long_on":"okx","short_on":"dydx","per_8h_usd":2.9,"per_day_usd":8.7,"per_30d_usd":261,"taker_fees_round_trip_usd":20,"breakeven_hours":55.2,"assumptions":"taker 0.05% per leg on both venues, open and close; spread held constant; no slippage, no basis move"},"read":"ETH funding 0.0390%/8h on dydx vs 0.0100% on okx — 2.9 bps/8h, 77th percentile of the last 7 days (7 of 9 venues answered)","venues_unavailable":{"binance":"geo-blocked (451)","bybit":"geo-blocked (403)"}}

Inputs: symbol (required), notional_usd.
Get current Ethereum gas prices (slow, standard, fast)
Use when: You need to know current Ethereum gas prices before submitting a transaction or estimating costs. Not for: you need gas as part of a broader read — market_snapshot already includes standard gwei; only Ethereum mainnet gas is reported. Returns: slow_gwei, standard_gwei, fast_gwei, base_fee_gwei, estimated confirmation times Example response: {"slow_gwei":1.5,"standard_gwei":2,"fast_gwei":3,"base_fee_gwei":1.2,"source":"etherscan"}
Price: $0.000 USDC per call
Inputs: no named parameters.
Fed rate, inflation proxy, S&P 500, BTC, ETH, and gas in one call. Replaces three separate API integrations with a single normalized response — the only tool that gives you macro + crypto in one shot.
Use when: You need a combined macro + crypto market overview in one call: S&P 500, Treasury yield, BTC, ETH, and Ethereum gas. Not for: you need one asset in depth — token_price, gas_tracker or funding_rates; history or time series — dune_query. Returns: sp500_price, sp500_change_pct, treasury_yield_10y, btc_price_usd, eth_price_usd, gas_standard_gwei, timestamp Example response: {"sp500_price":5234.18,"sp500_change_pct":-0.42,"treasury_yield_10y":4.31,"btc_price_usd":67200,"eth_price_usd":3450,"gas_standard_gwei":5.2,"timestamp":"2026-05-26T12:00:00Z","source":"yahoo_finance+coingecko+etherscan"}

Inputs: no named parameters.
Get total open interest in perpetual futures for any asset, with 1h and 24h change rates. Pairs with funding_rates to complete the derivatives picture — rising OI with high funding = overcrowded position.
Use when: You need to know total open interest in perpetual futures and whether it's rising or falling. Combine with funding_rates for a full derivatives picture. Not for: you need the funding cost of holding a position — funding_rates; a single trade verdict — pre_trade_check. Returns: total_oi_usd, oi_change_1h_pct, oi_change_24h_pct, long_short_ratio, per-exchange breakdown Example response: {"asset":"ETH","price_usd":2069.73,"total_oi_usd":8420000000,"oi_change_1h_pct":1.2,"oi_change_24h_pct":12.4,"long_short_ratio":1.08,"long_short_ratios":{"Binance":1.08,"OKX":1.11,"Gate.io":1.02},"long_short_spread":0.09,"exchanges":[{"exchange":"Binance","oi_contracts":4066123.5,"oi_change_1h_pct":1.2,"oi_change_24h_pct":12.4,"long_short_ratio":1.08}],"source":"binance/bybit/okx + gate/bitget (L/S)","primary":"binance"}

Inputs: asset.
Get real bid/ask depth and slippage estimates at $10k, $50k, and $250k notional from Binance, Bybit and OKX. Use before sizing a position to know if you can execute without moving the market.
Use when: You need to estimate slippage before executing a large trade. Tells you how much a $10k, $50k, or $250k order will move the market. Not for: you need market cap or 24h volume — token_market_data; a full pre-trade verdict at your size — pre_trade_check. Centralised-exchange books (Binance/Bybit/OKX) only, not DEX pools. Returns: best_bid, best_ask, spread_pct, depth with slippage_pct at $10k/$50k/$250k notional, per-exchange best prices Example response: {"asset":"ETH","pair":"ETH/USDT","best_ask":2071.5,"best_bid":2071.2,"spread_pct":0.0145,"depth":[{"notional_usd":10000,"slippage_pct":0.002,"executable":true},{"notional_usd":50000,"slippage_pct":0.008,"executable":true},{"notional_usd":250000,"slippage_pct":0.031,"executable":true}],"exchanges":[{"exchange":"Binance","best_ask":2071.5,"best_bid":2071.2},{"exchange":"Bybit","best_ask":2071.6,"best_bid":2071.1}],"source":"binance/bybit/okx"}

One-call pre-trade sanity check: 'I want to long $X of SYMBOL — is now sane?' Combines live orderbook slippage at YOUR size, cross-exchange funding (carry cost), open-interest crowding, and contract security (GoPlus) into a single ok/caution/avoid verdict with a per-factor breakdown. Major ERC-20 addresses (LINK, UNI, ARB, OP, AAVE, PEPE, SHIB) resolve automatically; native assets (BTC, ETH, SOL, ...) report security n/a; an unrecognized token without token_address reads 'unknown' and caps the verdict at caution — an unscreened contract can never read 'ok'. Replaces four API integrations and the judgment layer on top of them. Raw component data embedded so you can apply your own thresholds. Stacks tokens (STX, sBTC, USDCx, stSTX, ZEST, LEO, USDh, aeUSDC, stBTC) add the Bitflow DEX venue: price impact at YOUR size from a live route quote, the pools and bins the swap crosses, and their TVL; STX and sBTC keep their CEX perp legs, DEX-only tokens report funding/OI n/a and contract risk unscreened (no GoPlus coverage on Stacks).
Use when: An agent (or human) is about to enter a position and wants one verdict covering liquidity, carry, crowding, and security — instead of four raw feeds plus its own synthesis. Not for: you need a single raw factor — funding_rates, open_interest, orderbook_depth or token_security are free; you are not about to size a position. This call settles $0.01 on-chain. Returns: verdict (ok/caution/avoid), factors{liquidity,carry,crowding,security} each with level + reason, components{orderbook_depth,funding_rates,open_interest}, symbol, side, size_usd Example response: {"symbol":"ETH","side":"long","size_usd":50000,"venue":"cex","verdict":"caution","factors":{"liquidity":{"level":"ok","slippage_pct":0.011,"bucket_usd":50000,"reason":"fills within 0.011% of best ask"},"carry":{"level":"caution","median_funding_pct":0.062,"annualized_pct":67.9,"reason":"longs paying elevated funding"},"crowding":{"level":"ok","long_short_ratio":1.4,"oi_change_24h_pct":3.2,"reason":"positioning unremarkable"},"security":{"level":"n/a","reason":"ETH is a native chain asset — no token contract to screen"}},"not_checked":["security"]}

Inputs: symbol (required), side, venue, size_usd, +1 more.
Legacy alias of verified_route (kept for back-compat). Find and judge the best paid x402 tool for a need, within a budget. Discovers across Coinbase Bazaar, drops stubs (no schema / factory clones), ranks survivors by real usage (unique payers × 3 + calls + recency bonus), enforces the budget, price- tiebreaks quality-equal candidates. Returns ranked candidates + a recommendation + ready-to-pay details. Advise-only — no payment happens here. Prefer verified_route (same vetting, matches the paid tool + Bazaar listing). Use when: "which x402 tool for X", "find a paid API for X under $Y".
Inputs: need (required), budget.
The sBTC peg as an agent-readable feed — the one dataset only Stacks state can answer. Live sBTC supply (and share of the peg cap), peg-in and peg-out flows for 24h and 7d (sats, counts, unique recipients, net), in-flight bridge requests (pending and accepted deposits with the oldest pending age, pending withdrawals, 24h failures), the last peg events with Bitcoin txids, the signer set and signature threshold, and the rolling withdrawal cap with its current headroom. Read from the sBTC token and registry contracts and the bridge API (Emily); a source that fails degrades to null plus a note. Signer liveness is not public and is reported as null — the pending ages and withdrawal headroom are the proxies.
Use when: An agent wants the state of the sBTC peg before moving BTC onto or off Stacks, sizing against the withdrawal cap, or reading Bitcoin-capital flow into Stacks as a signal. Not for: you need the sBTC price or market data — token_price / token_market_data are free; you need a swap quote — pre_trade_check prices Bitflow. This call settles $0.01 on-chain. Returns: asset, contract, network, as_of{time, stacks_height, bitcoin_height}, supply{sats, btc, peg_cap_sats, pct_of_cap}, flows{24h, 7d}{peg_in_sats, peg_in_count, peg_in_unique_recipients, peg_out_sats, peg_out_count, net_sats, from_stacks_height, complete}, in_flight{deposits_pending, deposits_accepted, oldest_pending_deposit_age_hours, withdrawals_pending, withdrawals_accepted, deposits_failed_24h, withdrawals_failed_24h}, last_events[{type, sats, stacks_height, bitcoin_txid, recipient|sender}], signers{count, signature_threshold, aggregate_pubkey, limits{peg_cap_sats, per_deposit_minimum_sats, per_withdrawal_cap_sats, rolling_withdrawal_cap_sats, rolling_window_blocks, available_to_withdraw_sats, withdrawal_headroom_pct, throttle_mode}, liveness, note}, read, sources, notes[] Example response: {"asset":"sBTC","contract":"SM3VDXK3WZZSA84XXFKAFAF15NNZX32CTSG82JFQ4.sbtc-token","network":"stacks-mainnet","as_of":{"time":"2026-11-05T13:16:06+00:00","stacks_height":9418770,"bitcoin_height":974675},"supply":{"sats":248402294199,"btc":2484.02294199,"peg_cap_sats":2100000000000000,"pct_of_cap":0.0118},"flows":{"24h":{"peg_in_sats":349000521,"peg_in_count":870,"peg_in_unique_recipients":11,"peg_out_sats":172451573,"peg_out_count":15,"net_sats":176548948,"from_stacks_height":9411041,"complete":true},"7d":{"peg_in_sats":1093108934,"peg_in_count":5324,"peg_in_unique_recipients":39,"peg_out_sats":790710098,"peg_out_count":110,"net_sats":302398836,"from_stacks_height":9359229,"complete":true}},"in_flight":{"deposits_pending":10,"deposits_accepted":16,"oldest_pending_deposit_age_hours":50,"withdrawals_pending":0,"withdrawals_accepted":3,"deposits_failed_24h":0,"withdrawals_failed_24h":1},"last_events":[{"type":"peg_in","sats":85000,"stacks_height":9418744,"bitcoin_txid":"62acd3f2cee3b1bb0ba547de0d1fc32253bf69e79b63cf19f9e055dc97f741db","recipient":"SP000000000000000000002Q6VF78.pox-5"}],"signers":{"count":11,"signature_threshold":8,"aggregate_pubkey":"0x02d99ad0f0111a7e9aaa2ed22940efec98db0ece9b9475e61e1eec65a6e7f3af69","limits":{"peg_cap_sats":2100000000000000,"per_deposit_minimum_sats":10000,"per_withdrawal_cap_sats":5100000000,"rolling_withdrawal_cap_sats":15100000000,"rolling_window_blocks":150,"available_to_withdraw_sats":14786411900,"withdrawal_headroom_pct":97.9,"throttle_mode":null},"liveness":null,"note":"signer liveness is not published; the observable proxies are pending/accepted deposit ages and the rolling withdrawal headroom"},"read":"sBTC supply 2484.02 BTC; 24h net +1.7655 BTC (870 in / 15 out); 7d net +3.0240 BTC (5324 in / 110 out); 10 deposits pending (oldest 50.0h); 8-of-11 signers; withdrawal headroom 97.9%","notes":[]}

Open a budget-capped agent session on AgentPay. Pay $0.01 USDC once — get a session_id, budget config, and gateway URL. Enforces a hard max_spend cap across all subsequent tool calls via the AgentPay SDK. The entry point for agents discovering AgentPay on Base Bazaar.
Use when: You want to start an AgentPay session with a hard spend cap and get a session_id for tracking.
Not for: you only need a session for free tools — the SDK's quickstart() opens one at no cost; this call settles $0.01 on-chain.

Get market cap, 24h volume, ATH, and price change for any token. Note: does NOT return pool depth or slippage — for pre-trade liquidity estimates, use a dedicated orderbook tool.
Use when: You need 24h trading volume, market cap, or all-time high for a token pair on decentralized exchanges. Not for: you only need the spot price — token_price is lighter; you need pool depth or slippage — orderbook_depth. Returns: volume_24h_usd, market_cap_usd, price_usd, ath_usd, price_change_24h_pct Example response: {"token_a":"ETH","token_b":"USDC","price_usd":2071.45,"volume_24h_usd":312847293,"volume_change_24h_pct":-8.3,"market_cap_usd":249800000000,"ath_usd":4878.26,"price_change_24h_pct":-3.91,"source":"coingecko"}

Get the current USD price of any cryptocurrency token
Use when: You need the current USD price, 24h change, or market cap of any cryptocurrency. Not for: you need volume, ATH or a pair quote — token_market_data; a one-call macro + crypto overview — market_snapshot; pool depth or slippage — orderbook_depth. Returns: price_usd, change_24h_pct, market_cap_usd, coin_id Example response: {"symbol":"ETH","price_usd":2069.73,"change_24h_pct":-4.04,"market_cap_usd":250330787714.19,"source":"coingecko"}

Scan any token contract for honeypot, rug pull, and security risks
Use when: You need to check if a token contract is safe before trading or investing. Not for: the asset is a native coin (BTC, ETH, SOL) with no contract — nothing to scan; you want liquidity or price — orderbook_depth / token_price. Ethereum and BSC contracts only. Returns: risk_level, is_honeypot, buy_tax, sell_tax, holder_count, owner_address, is_mintable, can_take_back_ownership Example response: {"contract_address":"0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2","chain":"ethereum","risk_level":"low","is_honeypot":false,"buy_tax":0,"sell_tax":0,"holder_count":842341,"is_mintable":false,"can_take_back_ownership":false,"source":"goplus"}

Convert any URL to clean, LLM-ready markdown. Strips ads, nav, and boilerplate — returns just the content. No API key needed.
Use when: You need to read the content of a web page or article and get clean, structured text for further processing.

Paid buyer-side trust oracle: 'I need X, budget $Y — which x402 tool is real?' Sweeps the WHOLE x402 marketplace across many queries (a single search shows only a slice), collapses sybil/factory clusters (one wallet stamping many fake-distinct listings → one entry), ranks the genuinely-used survivors by real unique-payer usage, and returns ONE vetted recommendation with a ready-to-pay x402 challenge. The credit-bureau check an agent cannot do itself in one query — pay $0.01 to avoid paying a scam or a dead stub.
Use when: An agent is about to pay an unknown x402 tool and wants the real, used, non-sybil one under budget — not just the cheapest. Not for: you already know which AgentPay tool you need — call it directly; you only want a free preview of the marketplace ranking — the MCP's free preview (verified_route_preview on the remote server). This call settles $0.01 on-chain. Returns: recommendation (with ready_to_pay), survivors[] (each with typed evidence[]), catalog{scanned, real_providers, sybil_collapsed, biggest_factory}, vetting summary Example response: {"need":"dex pair liquidity","chain":null,"budget_usd":"1","recommendation":{"name":"Otto AI","url":"https://otto.example/dex","price_usd":"0.001","network":"eip155:8453","pay_to":"0x0e84ddedaae6a7","payers30d":200,"calls30d":3246,"quality":3851,"flags":[],"evidence":[{"type":"delivery","source":"agentpay-prober","metric":"delivery_rate","value":1,"n":12,"observed_at":"2026-09-30T13:05:00Z","ref":"/s/otto-example-dex-1a2b3c"},{"type":"third-party","source":"coinbase-bazaar","metric":"unique_payers_30d","value":200,"observed_at":"2026-10-01T12:00:00Z","ref":null}],"ready_to_pay":{"url":"https://otto.example/dex","network":"eip155:8453","price_usd":"0.001","accepts":{"scheme":"exact","network":"eip155:8453"}}},"survivors":[],"catalog":{"scanned":117,"after_vetting":114,"real_providers":41,"unique_wallets":38,"sybil_collapsed":73,"biggest_factory":{"pay_to":"0x2bb72231eed3","listings":72}},"vetting":"swept 17 queries → 117 listings → collapsed 73 sybil listings → 41 real providers"}
Price: $0.01 USDC per call (x402 over MCP: an unpaid call returns PaymentRequired; pay via _meta x402/payment)
Inputs: need (required), chain, budget_usd.
Buyer-side trust oracle for the x402 marketplace: "I need X, budget $Y — which tool is real?" Vets Coinbase Bazaar (discover → drop stubs/factory clones → rank by real unique-payer usage → budget-gate). This MCP runs the FREE single-query PREVIEW: it returns the vetted pick (name + usage stats + why) and survivor count to PROVE a real provider exists, but WITHHOLDS the provider URL + ready-to-pay x402 challenge. To get those — plus the full multi-query sweep + usage-based sybil-collapse + trust allowlist — call verified_route ($0.01: an unpaid call returns the x402 PaymentRequired, which a wallet-carrying client pays in-band), or use the agentpay-x402 SDK. This preview never charges. Use when: "which x402 tool for X", "find a real/trustworthy paid API for X", "avoid a scam or dead stub", "vet this provider before I pay".
Inputs: need (required), chain, budget_usd.
Get the token balances for any Ethereum or Stellar wallet address
Use when: You need to look up the token holdings of an Ethereum or Stellar wallet address. Not for: you want a token's price or market data rather than one address's holdings — token_price / token_market_data; large transfers across many wallets — whale_activity. Ethereum addresses are 0x…, Stellar addresses G…; no other chains. Returns: list of token balances (symbol, amount) for the given address Example response: {"address":"0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045","chain":"ethereum","balances":[{"token":"ETH","amount":"1.234"},{"token":"USDC","contract":"0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48","amount":"500.00"}]}
Price: $0.000 USDC per call
Inputs: chain (required), address (required).
Search the web and return the top 5 results with their full content as clean markdown. Better than DIY because zero setup and results include page content, not just links.
Use when: You need to find current information on any topic — news, documentation, prices, events, or anything else on the web. Not for: you already have the URL — url_reader; you want crypto headlines with sentiment — crypto_news. Returns: results[] with url, title, description, content; query; count Example response: {"query":"ETH gas fees today","count":5,"results":[{"url":"https://etherscan.io/gastracker","title":"Ethereum Gas Tracker","description":"Real-time Ethereum gas price tracker","content":"Current gas: 2 Gwei..."}],"source":"jina_search"}
Price: $0.000 USDC per call
Inputs: query (required).
Detect recent large wallet movements for a token (whale tracking)
Use when: You need to detect large token transfers that may signal institutional moves, accumulation, or sell-offs. Not for: you need one address's holdings — wallet_balance; exchange order-book size rather than on-chain transfers — orderbook_depth. Ethereum ERC-20 transfers only. Returns: large_transfers[] with from, to (full addresses), amount, usd_value, minutes_ago, tx_hash; total_volume_usd Example response: {"token":"USDC","large_transfers":[{"from":"0xabababababababababababababababababababab","to":"0xcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcdcd","amount":5000000,"usd_value":5000000,"minutes_ago":12,"tx_hash":"0x9f9f9f9f9f9f9f9f9f9f9f9f9f9f9f9f9f9f9f9f9f9f9f9f9f9f9f9f9f9f9f9f"},{"from":"0x1111111111111111111111111111111111111111","to":"0x2222222222222222222222222222222222222222","amount":2500000,"usd_value":2500000,"minutes_ago":34,"tx_hash":"0x7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a7a"}],"total_volume_usd":7500000,"source":"etherscan"}
Price: $0.000 USDC per call
Inputs: token (required), min_usd.
Find best DeFi yield opportunities across protocols for a given token
Use when: You need to find the best yield/APY for a token across DeFi protocols. Not for: you need a protocol's total TVL rather than pool APYs — defi_tvl; risk_level is a heuristic, run token_security on the pool's token before depositing. Returns: list of pools with protocol, apy, tvl_usd, chain, risk_level sorted by APY descending Example response: {"token":"USDC","pools":[{"protocol":"morpho","apy":8.74,"tvl_usd":312000000,"chain":"Ethereum","risk_level":"low"},{"protocol":"aave-v3","apy":5.21,"tvl_usd":1840000000,"chain":"Ethereum","risk_level":"low"},{"protocol":"compound-v3","apy":4.87,"tvl_usd":920000000,"chain":"Ethereum","risk_level":"low"}],"source":"defillama"}
Price: $0.000 USDC per call
Inputs: token (required), chain, min_tvl.
