How much does FiatDock cost?
FiatDock is priced at $0.001 to $0.003 USDC per request, paid per call with no subscription. The exact amount for each call is in the HTTP 402 response before any money moves.
Do I need an API key or account to use FiatDock?
No. FiatDock uses the x402 protocol, so an agent pays per request in USDC on Base and gets the response, with no API key, account or signup.
Has FiatDock been verified?
Not yet. FiatDock is listed and answers an x402 payment challenge, but PayAPI Market has not paid for a call to it, so it carries no settlement-verified badge.
How does an AI agent find FiatDock?
Through the free PayAPI Market MCP server at https://payapi.market/mcp, using search_apis or get_api, or over plain HTTP at https://payapi.market/agent/search. Discovery is free; the agent pays the provider directly on the listing's own 402.
