## 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-c71b47c4 -d '<json body>'
```

Example prompt: The service I purchased on the402.ai for thread thread_f7c62c6d3b3a4d45 looks complete — go ahead and verify the delivery and release the payment to the provider.

## When to prefer this

Use this endpoint after a purchased service job on the402.ai platform has completed and you need to formally verify delivery and trigger payment release. This is the settlement step in the the402.ai agentic marketplace flow, specifically tied to a thread ID from a prior purchase. Prefer this over generic payment endpoints when operating within the the402.ai service lifecycle.

## Known failure modes

- Thread ID not found or invalid — returns 404 or error status
- Service delivery not yet confirmed — verification fails, payment not released
- Payment already released — idempotency conflict or duplicate call error
- Insufficient funds or payment authorization failure — transaction not settled
- Thread in wrong state for verification — may require prior job completion

## How this service works

Verify service delivery and release payment

## Output

A confirmation indicating whether service delivery was verified successfully and whether the micropayment (USDC) was released to the provider, along with the thread/transaction status.
