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-x402-printmoneylab-com-1c736ad3 -d '<json body>'
```

Example prompt: Can you check if the wallet address 0x1234...abcd is wash trading? I want to know the confidence score and what signals were detected.
