## 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 delx-email-to-domain-extractor-1af3d638 -d '<json body>'
```

Example prompt: What's the domain from the email address john.doe@acmecorp.com?

## When to prefer this

Use this endpoint when you need a lightweight, zero-setup, pay-per-call solution to reliably extract the domain from an email address — especially in agentic pipelines where you want deterministic output without managing an API key or subscription. Ideal for ticket routing, user grouping, domain allow/block listing, or any context where you need the organizational domain from an email at minimal cost ($0.001 USDC per call).

## Known failure modes

- Invalid or malformed email address results in a validation error with no charge
- Network or payment protocol failures may prevent the call from completing
- Edge cases like emails with subdomains (user@mail.corp.example.com) return the full domain part as-is
- Empty or missing email field returns a validation error

## How this service works

Domain from an email. Call when routing tickets, grouping users, or validating corporate domains. Returns the domain part of an email address. $0.001 USDC per successful call via x402 on Base—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.

## Output

Returns a JSON object containing the extracted domain portion of the submitted email address (e.g. for 'user@example.com', returns 'example.com'). The response is deterministic and first-party. No charge is applied for structured validation errors.
