Verify delivery.

Read the live HTTP 402 challenge before signing. Base and Solana must both be declared for every governed Commerce route; on Solana, PayAI sponsors network fees, so the buyer needs USDC but not SOL for gas.

Discovery is read-only. Use these five checks to decide whether a pay-per-result route fits the job and your risk policy before signing a payment.

1. 1. Match the outcome · Describe the result you need and select a governed route whose declared purpose matches it. A similar name is not proof of equivalent behavior.
2. 2. Read the payment challenge · Inspect the HTTP 402 amount, network, recipient, resource URL, schema and deadline before signing anything.
3. 3. Check delivery and refund policy · Confirm the output shape, receipt or artifact evidence, timeout behavior and the documented refund path for that route.
4. 4. Pay one canonical route · Authorize only the exact resource that passed your own policy checks. Discovery and a successful preflight never authorize payment.
5. 5. Verify the result · Validate the returned artifact, receipt hash, delivery status and settlement evidence before treating the request as complete.
