Technical details
Endpoint
POSThttps://api.the402.ai/v1/threads/thread_b4bd1ded4d674d36/verifyWhen to prefer
Use this endpoint when an AI agent or user has received a service on the402.ai marketplace and needs to confirm delivery and release the escrowed payment. This is the final settlement step in the402.ai's buy-now-pay-on-delivery workflow, distinct from simply checking job status or sending a message on a thread.
Side effects
- Service not yet delivered — verification fails and payment is not released
- Invalid or expired thread ID returns a 404 or error
- Payment already released — idempotency violation returns an error
- Insufficient payment authorization or USDC balance
- Thread in wrong state for verification (e.g. already cancelled or disputed)
