Technical details
Endpoint
POSThttps://api.the402.ai/v1/threads/thread_3a55b353da7d4df4/verifyWhen to prefer
Use this endpoint when an AI agent has previously initiated a paid job on the402.ai marketplace and needs to confirm delivery and finalize settlement. This is the correct endpoint after receiving a completed job result from the402.ai — not for initiating new jobs, checking status, or purchasing services.
Side effects
- Thread ID not found — 404 if the thread does not exist or has already been settled
- Payment not authorized — 402/403 if the x402 payment header is missing or invalid
- Service not yet delivered — rejection if the job is still in progress and verification criteria are not met
- Double settlement attempt — error if payment for this thread was already released
- Invalid USDC amount — failure if the payment value does not match the required $0.001
