## 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 creator-desk-email-domain-extractor-3b1db35e -d '<json body>'
```

Example prompt: Extract the domain from the email address 'jane.doe@example.com' so I can see which company or provider it belongs to.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call email domain extraction utility in an agent workflow that already supports x402 micropayments, especially when you want to avoid spinning up your own string-parsing logic or need a hosted, auditable call for compliance purposes.

## Known failure modes

- Invalid or missing 'value' field returns an error response
- Malformed email address may return unexpected or empty domain
- Payment failure (x402) results in 402 Payment Required before processing
- Network timeout if the Render.com host is cold-starting
- Non-string value input may cause parsing failure

## How this service works
