X402 API Overview
The x402-api MCP server is based on x402, an open standard for attaching payments to HTTP resource requests. It defines a flow in which clients receive payment requirements, submit signed payment payloads, and obtain resources after verification and settlement. The protocol supports multiple payment schemes and network implementations, with reference SDKs for TypeScript, Python, and Go. Reach for it when an HTTP API needs a documented payment-required flow rather than an external checkout process.
Primary Use Cases for X402 API:
- Protect HTTP API routes with payment requirements
- Request paid resources through signed payment payloads
- Verify payments through local logic or a facilitator
- Settle supported payments on a blockchain
