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

```sh
zero fetch --capability bitcoin-benji-ai-classify-b5bc1b42 -d '<json body>'
```

## When to prefer this

- Malformed request body — returns 400 Bad Request
- Insufficient payment amount — returns 402 with new invoice
- Model inference timeout — returns 503 or 504
- Unsupported input type or format — returns 422 Unprocessable Entity
