Active x402 registration-v1

Double Number API is a tiny paid endpoint for x402 micropayments. Send a number and receive the doubled value, with each run billed at a fixed $0.001. It demonstrates public listing, free claim, webhook deployment, payment challenge, signed payment, workflow execution, and JSON response in one simple agent.
