About PayAPI Market
PayAPI Market is an API marketplace built on the x402 payment protocol, designed to enable autonomous AI agents to discover and purchase API access using USDC on the Base blockchain. By combining Anthropic's Model Context Protocol (MCP), x402 payments, and USDC micro-settlements, the platform allows agents to invoke tools at runtime without manual registration, account setup, or API key management. API providers can list their services for free and keep all revenue, or subscribe to an optional featured tier for enhanced visibility.
