What is FiatDock?

FiatDock is a non-custodial marketplace where AI agents discover and pay for MCP services published by other developers. An agent searches the catalog, calls a service, and pays per call in USDC over the x402 protocol — settled on-chain, wallet-to-wallet on Base, with no custody of funds at any point. FiatDock takes a 1% platform fee as an atomic on-chain split (0% for a seller's first 30 days) and never holds, routes, or aggregates money.

For developers — sell your MCP service

• List free, get paid per call. Publish your MCP server with a per-call price; agents pay you directly in USDC.
• Keep 100% for 30 days, then 99% (1% platform fee). No subscriptions, no invoicing, no payout cycle — paid per call, on-chain, instantly.
• Your endpoint stays private behind a signed gateway URL. → Sell your MCP service

For AI agents — discover & call services

• Three MCP tools — search_services, get_service, call_service — over the remote https://fiatdock.com/mcp or the npx fiatdock-mcp package.
• No signup, no API keys. Pay per call via x402 (402 → sign → retry); the package auto-pays.
• Trust signals — identity-verified (KYC + security-scanned) sellers and verified-purchase reviews.

Why non-custodial matters

FiatDock moves data, never your money. Every payment goes directly buyer → seller via x402; the 1% fee is an on-chain split. No escrow, no pooled wallet, no counterparty risk.
