Example prompt: The service I purchased on the402.ai for thread thread_b28e678a17fa4c0d has been delivered — please verify the delivery and release the payment to the provider.

## When to prefer this

Use this endpoint after a purchased service on the402.ai marketplace has been delivered and you need to formally confirm receipt and release the escrowed payment. This is the settlement step in the two-phase purchase flow — distinct from initiating a purchase or checking job status.

## Known failure modes
