## 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-commerce-email-domain-extractor-a11c4a82 -d '<json body>'
```

Example prompt: What's the domain part of the email address agent@example.com?

## When to prefer this

Use this endpoint when you need a simple, cheap, pay-per-call extraction of the domain from an email address without any signup or subscription overhead — particularly in agent workflows using x402 micropayments on Base or Solana where you want verifiable, per-result billing at $0.001 USDC per call.

## Known failure modes

- Invalid or malformed email address returns an error or empty domain field
- Missing 'email' field in request body causes a 400-level error
- Non-email string input may fail format validation
- Network or payment failure (x402) prevents the call from completing

## How this service works
