• getAccountBalanceA

  Ankr Agent RPCA

  Balance of an account across many blockchains, by 0x address or ENS name, via the Ankr Advanced API indexer. Assets are ranked by USD value descending and only the top 20 are listed by default (a real wallet can hold 1000+ assets, over half of them priced at $0); tune that with maxTokens/minUsd, or call getBalances for structured JSON. Anything the indexer PRICED at zero or below minUsd is summarised as a dust count instead of being listed. An asset with NO indexer price is not dust: it reads "USD value unknown" and ranks after every priced asset, so on a wallet holding more priced assets than maxTokens none appear here and the note says how many exist off-page. Unknown is not zero. An implausibly large raw balance (typical of scam tokens minting max-uint) is flagged and its balance is withheld; never add it to a total. Each line names the chain the asset is held on, which matters because omitting `blockchains` queries EVERY chain and interleaves the result across them.

• get_onramp_urlA

  OpenFinance — Easy Trading: Crypto, Stocks, Perps & Prediction MarketsA

  The ONE fiat-to-crypto onramp tool. The backend picks the right provider based on `baseCurrency` — agents should NOT think about which provider to use. Use this whenever the user wants to deposit fiat / buy crypto / top up / add funds — e.g. 'I want to buy USDC', 'top up my wallet with $100', 'deposit ₹1000', 'add ₹5000 USDC', 'buy USDC with INR', 'onramp $50', 'add funds with UPI/IMPS', 'add funds with credit card', 'buy ETH on Base', 'get USDT with INR'. Provider routing (handled server-side, do not mention to the user unless they ask): - baseCurrency = 'inr' → Onramp.money (UPI / IMPS / RTGS, India-first) - anything else / default → Moonpay (global cards & bank transfers) Wallet address defaults to the caller's Privy-provisioned wallet for the chosen chain (EVM by default; Solana when chain=solana). Email is auto-pulled from Privy on the Moonpay branch. Returns { provider, url, ... } — hand the URL to the user to open in browser/iframe. INR (Onramp.money) coin × network matrix — when baseCurrency='inr' pass a `chain` matching one of these or the call rejects: usdt → ethereum, polygon, bsc, tron usdc → polygon, bsc (NOT ethereum, NOT solana) busd → bsc matic → polygon bnb → bsc eth → ethereum, polygon sol → solana If the user asks for a pair outside this matrix on INR, propose a supported chain — e.g. 'buy USDC with INR on Ethereum' → polygon is the only INR option for USDC, suggest that.

• chain_balanceA

  Wicked MCPA

  [Trading Data API] Native-token balance (ETH/POL) for any address or ENS name on Ethereum, Base, Arbitrum, Optimism or Polygon. Live from the chain over redundant RPCs — wei plus formatted units. **Example:** `/v1/chain-balance?address=vitalik.eth&chain=ethereum` Use when you need the native-token balance (ETH/POL) of an address or ENS name on Ethereum, Base, Arbitrum, Optimism or Polygon. Not for token balances (use chain_token_balance) or a full holdings view (use wallet_portfolio). Behavior: read-only. Priced via x402 (USDC on Base) or free with WICKEDAPI_API_KEY; with neither, you get HTTP 402 with the decoded price in payment_required (a price quote, not a failure).

• portal_resolve_entityA

  SQDA

  Resolve user-facing blockchain entities into query-ready identifiers, with ambiguity kept explicit. COMMON USER ASKS: - Resolve USDC on Base - Resolve WETH on Ethereum - Resolve BAYC contract FIRST CHOICE FOR: - resolving a token symbol like USDC to token contract addresses - resolving EVM contract aliases, protocol names, pool identifiers, or Hyperliquid coin names before querying - checking which token-list addresses a symbol maps to before querying logs or transfers - turning a user-friendly token name into deterministic EVM filters WHEN TO USE: - The user names a token symbol such as USDC, WETH, DAI, or PEPE and you need contract addresses before querying raw data. - The user names a well-known EVM contract, protocol, pool identifier, or Hyperliquid ticker and you need a deterministic follow-up filter. - You need to disambiguate bridged token variants on an EVM network. - You want a source-backed token address rather than relying on memory or hardcoded constants. DON'T USE: - You already have the exact address, pool id, protocol slug, or coin filter and can pass it directly. EXAMPLES: - Resolve USDC on Base: {"network":"base-mainnet","kind":"token","query":"USDC","limit":10} - Resolve WETH on Ethereum: {"network":"ethereum-mainnet","kind":"token","query":"WETH","limit":5} - Resolve BAYC contract: {"network":"ethereum-mainnet","kind":"contract","query":"bored apes"} - Resolve Hyperliquid coin: {"kind":"hyperliquid_coin","query":"bitcoin"}

  Tokenbooks - crypto and fiat accounting and paymentsA

  Learn what this accounting server covers before connecting: supported blockchains and fiat sources, accounting standards, plans with their capacity limits and what each tier adds, how to sign up, connection endpoint and authentication methods, and what it deliberately leaves out. Needs no credentials, so call it first when evaluating a connection, answering what Tokenbooks costs or includes, or debugging a connection.

• get_gas_priceA

  TeardropA

  Get current EIP-1559 gas fees on Ethereum or Base: base fee, priority fee, next-block base fee estimate, and congestion (gas_used_ratio >0.5 busy, >0.9 very congested). Optional USD estimates cover a simple transfer and a swap-like transaction. Cached 10 seconds per chain. Use when: Use before advising a transaction — to time execution, size a gas budget, or judge congestion. Call once per decision; the 10-second cache makes rapid re-calls pointless. Limitations: Point-in-time estimate that changes every block; USD figures are rough heuristics at 21k/150k gas, not an execution quote. Ethereum mainnet and Base only. Alternatives: get_block, get_dex_quote

• gas_trackerA

  AgentPay — trust routing + spend caps for x402 agentsA

  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

• wallet_balanceA

  TollkitA

  Check a wallet's balances on Base, Ethereum or Solana: native ETH or SOL, USDC (plus USDT on Ethereum and Solana), and any token contracts or SPL mints you list (up to 20), with symbols and decimals applied. Read live from the chain. $0.002 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. The first 3 calls a day through this tool server are free (no wallet needed). When to use: You need what a wallet holds, in token amounts. Use instead: wallet_portfolio for USD values and a total; check_my_balance (free) for your own USDC on Base. Parameters: address is required. chain: base (default), ethereum or solana; the address format must match. tokens: up to 20 extra ERC-20 contracts or SPL mints to include. Returns: native coin, USDC (USDT on Ethereum and Solana) and the tokens you listed, each with symbol, decimals and amount.

  Rozo CheckoutA

  Answers which cryptocurrencies and chains can pay an OpenRouter credit top-up or another AI service invoice through Rozo Checkout: USDC and USDT on Ethereum, BNB Chain, Polygon, Arbitrum and Solana; USDC on Base and Stellar; native ETH (Ethereum, Base, Arbitrum), BNB, POL and SOL; BTC over Lightning. Returns each chain id, token symbol and token decimals. Static list, needs no payment link and makes no network call; quote_invoice reports which of these a specific invoice accepts. Native coins (ETH on Ethereum, Base, Arbitrum; BNB on BNB Chain; POL on Polygon; SOL on Solana) are exact-out like Lightning: the order states the exact coin amount, priced at the current rate plus an FX spread on top of the service fee, and that price holds only until quoteExpiresAt. Native orders are capped at $3500 per invoice (native ETH on Ethereum needs at least $1), and a native coin is offered only when quote_invoice lists it for that invoice. ZEC on Zcash (Beta) is not available through this server: send a payer holding ZEC to https://checkout.rozo.ai/zec.
