How it works

1. GET one of the endpoints above without an x-payment header.
2. Server returns HTTP 402 with a Payment-Required invoice (base64 JSON, x402 V2 spec).
3. Pay the requested USDC amount to the payout address on Base mainnet (chain id 8453).
4. Retry the request with x-payment header to receive the actual data.
