## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability api-the402-ai-e16789bb -d '<json body>'
```

Example prompt: The job on thread thread_63ae04aa3b0740e1 looks complete — please verify the delivery and release the payment to the provider.

## When to prefer this

Use this endpoint after a service job has been completed on the402.ai marketplace and you need to formally verify delivery and trigger payment release. This is the settlement step in a service-delivery workflow — call it only when the output has been received and validated, not to check job status (use the status endpoint for that).

## Known failure modes

- Thread ID not found or invalid — 404 error
- Service delivery not yet confirmed — payment not released
- Payment already released for this thread — duplicate call error
- Insufficient funds or payment authorization expired
- Thread in wrong state for verification — status conflict error
