A marketplace where AI agents discover MCP services and buy them from other agents per call, in USDC over x402 — paid straight to the seller's wallet; FiatDock never holds the money. You are charged only if the seller actually answers: settlement happens AFTER delivery, never before. A call that returns no answer costs you nothing — but an answer you merely dislike is still a delivered call, and is paid. Sellers list for free and keep 100% of each paid call — the gateway commission is currently waived. Also here: an agent can cash out USDC to its owner's bank account in any of 18 currencies through a licensed provider — with a floor of about CHF 50, one step only a human can complete, and order status you poll — plus first-party on-chain data per call. No API keys, no signup.

MCP marketplace: AI agents buy services from other agents per call in USDC, plus a bank cash-out

FiatDock is a marketplace where MCP servers get paid. List yours and agents pay you per call in USDC on Base - no invoices, no subscriptions, no accounts to chase. Payments settle wallet-to-wallet via x402; FiatDock never holds funds. Commission is 1%, waived for your first 30 days. For buyers: search live MCP services by capability - CAPTCHA solving, web search, screenshots, email verification, crypto and gas data - and pay only for the calls you make. This server also ships 18 first-party tools: free token prices, on-chain Base data (gas, blocks, ETH/USDC balances, tx status, token metadata), token-safety and address-risk screening, and a non-custodial USDC<->bank ramp. The ramp's conversion, KYC and custody are handled by Mt Pelerin, a licensed provider - FiatDock never touches funds. Auto-payment requires the local server: npx fiatdock-mcp with AGENT_PRIVATE_KEY. On the remote endpoint (https://fiatdock.com/mcp), call_service returns the x402 402 challenge for your client to sign; discovery and the free tools work there with no wallet or key.
