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"
