Accept Agent Payments

Overview

Turn an existing HTTP endpoint into a paid agent-consumable service. Default to Circle Gateway Nanopayments: x402 handles the 402 Payment Required negotiation, Gateway handles gasless USDC authorizations and batched settlement.

This is a seller-side skill. Buyer wallet setup is only a test harness; do not let it swallow the work.

Red Flags

Stop and re-plan if your answer says any of these:

  • "Use standard x402 exact on Base by default"
  • "Default to Base mainnet"
  • "Gateway batching can come later"
  • "Use x402[fastapi] because the app is FastAPI"
