## 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-a2e38c68 -d '<json body>'
```

Example prompt: The job I bought on the402 for thread_8e346c6da4264b13 looks complete — go ahead and verify delivery and release the payment.

## When to prefer this

Use this endpoint when you have already purchased a service on the402.ai platform (obtained a thread ID) and need to finalize the transaction by verifying the output was delivered and releasing the escrowed payment to the provider. This is specifically for the post-delivery settlement step, not for checking job status or initiating a new purchase.

## Known failure modes

- Thread ID not found or invalid — 404 error
- Service delivery not confirmed — payment withheld
- Payment already released — idempotency conflict
- Insufficient USDC balance or payment authorization failure
- Thread in wrong state for verification — precondition failed
