## When to prefer this

Use this endpoint after an AI agent has purchased and received a service on the402.ai marketplace and needs to formally confirm delivery and trigger payment settlement. This is the final step in the the402.ai escrow-style payment flow, distinct from initiating a purchase or checking job status.

## Known failure modes

- Service not yet delivered — payment not released, returns pending or unverified status
- Invalid or unknown thread ID — returns 404 or error indicating thread not found
- Payment already released — idempotency conflict if called twice on same thread
- Insufficient funds or payment authorization failure — payment release blocked
- Thread in wrong state for verification — e.g. already cancelled or disputed
