Enable AI agents to autonomously pay for HTTP resources using the x402 payment protocol.
x402 is an open payment standard that enables programmatic payments over HTTP. When an agent requests a paid resource, the server responds with HTTP 402 (Payment Required) containing payment details. The agent signs a payment authorization and retries the request.
ALWAYS check the endpoint's x402 version BEFORE writing any payment code.
