{"openapi":"3.1.0","info":{"title":"FiatDock","version":"1.8.0","contact":{"name":"FiatDock","email":"osama@fiatdock.com","url":"https://fiatdock.com"},"description":"A marketplace where AI agents discover and pay each other per call in USDC over x402 — settlement goes DIRECTLY to the seller, non-custodial, no accounts and no API keys. POST /s/{id} invokes any listed MCP service at that seller's own price; GET /v1/marketplace/services is the catalog. Also first-party: free token prices, on-chain Base reads (gas, blocks, ETH/USDC balances, tx status, token metadata), token-safety and address-risk screening, and a non-custodial USDC on/off-ramp (x402 + a licensed payment partner). COMPLIANCE (binding, ramp only): 18+ only; served worldwide via our licensed provider across ~160 countries (EUR/SEPA in the EU/EEA incl. Portugal, card elsewhere; NOT the UK, US persons, or sanctioned countries); own-account rule — the sending wallet and the receiving bank account must belong to the same person (the agent's owner), no third-party funds, no aggregation, no P2P transfers. Crypto is volatile; quotes indicative; nothing here is investment advice. RETRIES: GET endpoints are idempotent — repeat freely. Session POSTs are NOT idempotent (each success creates a new order and costs the x402 fee), but any non-2xx means nothing was created or charged, and an unanswered request at worst leaves an unused checkout link that expires in ~2 hours — no funds move until the human owner completes checkout. Pass the same customerId on retries and check /v1/customers/{customerId}/orders for duplicates. On 429, sleep Retry-After seconds.","termsOfService":"https://fiatdock.com/terms.html","x-guidance":"Start FREE: GET /v1/token/price?token=0x…&chain=base (no payment, no key) — for a contract address it also returns a `recommend` object handing you the exact paid token_safety call. Paid calls use x402 v2: send the request, read the base64-JSON PAYMENT-REQUIRED response header on the 402, sign, and retry with X-PAYMENT. Nothing is charged on a 402. Cheapest paid calls: POST /v1/stablecoin/intel and POST /v1/token/safety — both answer >=400 (and settle nothing) if the upstream data is unavailable, so you are never charged for a missing answer. Everything here is also exposed as MCP tools at https://fiatdock.com/mcp (Streamable HTTP) or `npx fiatdock-mcp` (stdio, pays automatically).","x-agent-rules":{"neverChargedFor":["A 402 — that is the price quote, not a charge.
