x402 List

x402-list provides a comprehensive, independent directory for APIs that adhere to the x402 open HTTP 402 payment standard. This standard allows digital agents to execute payments on a per-request basis, enabling granular control over service consumption. Key features of the x402-list include: detailed endpoint pricing, supported payment networks, real-time monitored uptime derived from continuous live checks, and transparent settlement activity observed directly on-chain. Each submission to the directory undergoes a careful manual review to ensure accuracy and reliability for users. The data offered by x402-list is openly accessible under a CC BY 4.0 license. A free API is available for developers, alongside an MCP server that agents can query directly for instant access to service information. This platform is ideal for developers building agent-based systems, researchers analyzing payment flows, and service providers seeking to list their x402-compliant APIs to a targeted audience.
