Example prompt: The service for thread thread_fed528d57ad74489 on the402.ai has completed successfully — please verify delivery and release the payment to the provider.

## When to prefer this

Use this endpoint after a service job on the402.ai marketplace has completed and you need to formally verify delivery and release the escrowed USDC payment to the provider. This is the final step in the x402 payment flow for a specific thread — prefer it over generic payment endpoints when operating within the the402.ai service marketplace context.

## Known failure modes

- Thread ID not found — invalid or expired thread returns 404
- Service not yet complete — delivery cannot be verified if job is still in progress
- Payment already released — idempotency violation if called twice on same thread
- Insufficient funds or payment authorization failure — payment release blocked
- Unauthorized caller — requester does not have rights to verify this thread

## How this service works
