Search, negotiate and buy resource access with x402 test USDC on Ethereum Sepolia.
Pre-trade token safety check for AI agents. Simulates a sell before you buy, then returns one low/medium/high/unknown verdict with the signals behind it: sellability, buy/sell tax, liquidity depth, pair age, same-ticker impersonation, owner powers from bytecode. Ethereum, BSC, Base, Solana. Fail-closed - a check that cannot run answers unknown, never low. Publishes its own measured error rate with the benchmark harness in the repo. Free, no signup, no API key, MIT.
Pre-payment checks for AI agents. Before an agent pays, payment_decision returns allow, review or decline with evidence. Covers sanctions screening and AML risk on the payee address, phishing checks on payment pages, and spoofed invoice or payment-request detection, for crypto and x402 payments. Free, no API key.
The public record of building on Robinhood Chain — every ship with its source.
Skavio LLC serves 18 MCP tools. Four separately priced blockchain verification/DNS-TLS calls use native Circle USDC via x402 v2 on Base or Solana: Verify 0.02, Match 0.03, evidence PDF 0.05, DNS/TLS audit 0.05 USDC. Free discovery requires no wallet. Additional company document, OCR, invoice and audio relays use authenticated Agent Tools credentials and can debit prepaid company credits for eligible processing jobs. A human company admin may buy USD 5-500 Stripe card credit packs or top up with USDC at https://getskavio.com/agent-tools/dashboard.html. Those card credits DO NOT pay for the four standalone x402 USDC tools. Base-only HTTP x402 routes are separate. Endpoint: https://getskavio.com/mcp ; Docs: https://getskavio.com/agent-tools/docs.html ; USDC APIs: https://getskavio.com/x402/docs/ ; Support: support@getskavio.com. Evidence PDF is not a tax invoice. No real external paid card-to-MCP job E2E is verified yet.

Testnet wallet for AI agents on Aether: pay, get paid and buy from paid APIs, with spending caps.
Tessera turns the whole Hyperliquid perp universe into a single cross-section you can query. The hosted MCP server answers the questions a raw-data pipe can't: which markets are crowded, who is paying the most funding, how far one market's funding has diverged from ETH, what open interest and positioning look like across every market on the last completed day, and what the live market is doing right now. Nine tools — four ranking/screening tools, a series tool for one market, a coverage tool, the catalog/dictionary trio, and a live market read — over a completed-day rollup built from the venue's own trade feed. Rows and full history stay on the REST API: three Parquet datasets (order-flow-enriched 1-minute OHLCV, hourly funding, hourly positioning) partitioned per coin-month, downloadable with a key. Free keys work end to end; Pro removes the history and coverage limits.
Warden MCP lets AI agents find tokens, quote swaps and trade onchain on Base, BNB Chain, Robinhood Chain, Arc and Solana, within limits you set. Market tools need no credential: list_chains, search_tokens, trending_tokens, price_history, quote_swap and swap_status. Search by name, ticker or contract address, read USD price candles, and price a swap before committing to it, including cross-chain swaps. Wallet tools act for the wallet whose owner connected the agent, by OAuth sign-in or a wk_ key. agent_permissions shows what the agent may do and its daily limits. prepare_swap builds a trade and hands the owner a review link to sign. With request_session the owner turns on hands-free trading in one tap, and execute_swap then trades within the limits they set. swap_status tracks gasless and cross-chain trades. get_wallet shows holdings on every chain. Gasless trading is available on Base, BNB Chain and Robinhood Chain. Built by Warden Protocol, the team behind Warden Token Terminal.
402xAgent is the check an agent calls before paying any x402 endpoint. It probes the endpoint's 402 without paying and returns a pay / skip / recheck verdict with a reason. Every check leaves a public receipt. It never pays the target.

Check before money moves. Lorg Check tells an AI agent, or you, whether a token is a trap or an address is unsafe to pay, on Base and Ethereum. In live tests on new launches it blocked traps that GoPlus and Honeypot.is missed. Call check_token before buying or swapping into a token: it simulates a real buy and sell-back through the token’s own pool, reads what the creator can still do, who can pull the liquidity, and whether the creator was paid by a wallet behind earlier rugs. Call check_address before sending funds: sanctions, scam labels, EIP-7702 sweepers and address-poisoning look-alikes. Every answer is signed and says proceed, limit_exposure or do_not_proceed, with a one-line summary to show the user. Free key by GitHub sign-in, or connect with an API key.
