[01] ? WHAT_IS_X402

x402 is an open payment protocol that uses the HTTP 402 status code to enable instant, gasless stablecoin payments directly over HTTP. When a client requests a paid resource, the server returns a 402 response with payment requirements in the PAYMENT-REQUIRED header.

This tool validates that your endpoint correctly returns x402-compliant payment requirements.
