## 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-2bf42a9b -d '<json body>'
```

Example prompt: I've received the output from the the402.ai job on thread thread_6381fe7006164992 and it looks good — please verify the delivery and release the payment to the provider.

## When to prefer this

Use this endpoint after a purchased service on the402.ai marketplace has been delivered and you need to formally verify delivery and release the escrowed USDC payment. This is the settlement step in the the402.ai two-phase commerce flow (purchase → verify/release), specifically tied to a known thread ID. Choose this over generic payment APIs when operating within the x402 protocol and the402.ai service ecosystem.

## Known failure modes

- Thread ID not found or invalid — returns 404 or error indicating unrecognized thread
- Service delivery not yet confirmed — returns an error indicating the job is incomplete
- Payment already released — idempotency violation, may return conflict or duplicate error
- Insufficient escrowed funds — payment release fails with a balance error
- x402 payment header missing or malformed — returns 402 Payment Required
