I will build a pay-per-call API for your service (x402, USDC)

Monetize your API with per-call USDC payments using the x402 protocol (Base, Arc, or Solana): payment verification, replay protection, machine-readable service manifests, and deployment. My own pay-per-call services run live in production — I can demo them before we start. You receive working code, deployment support, and documentation.
