PayAPI Market
x402 marketplace for AI agents
Visit payapi.market →DocsPricing
A pay-per-call API marketplace built on the x402 protocol. Providers list APIs for free and keep 100% of each call's revenue; AI agents discover APIs via MCP or HTTP endpoints and pay per request in USDC on Base, Solana, or Algorand, with no API key, account, or subscription. Listings carry a settlement-verified badge when the operator has paid a real call and received an on-chain receipt. The site reports 886 live APIs across 6,126 endpoints, of which 875 are settlement-verified.
