## 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 email-reputation-check-1999c9b8 -d '<json body>'
```

Example prompt: Can you check the reputation and risk score of the email address 'john.doe@example.com' — I want to know if it looks legitimate or suspicious before approving this signup?

## When to prefer this

Use this endpoint when you need a quick, real-time reputation and risk score for a single email address — ideal for fraud prevention at signup, lead qualification, or filtering low-quality or disposable emails before sending campaigns. Prefer this over basic email syntax validators when you need behavioral and reputation signals, not just format checks.

## Known failure modes

- Invalid or malformed email address returns a validation error
- Missing required 'email' field returns a 400 Bad Request
- Unrecognized or brand new email domain may yield low-confidence scores
- Rate limit exceeded returns a 429 error
- Network timeout or upstream API unavailability returns a 503 error
