## 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 pennyrail-email-extractor-30afa847 -d '<json body>'
```

Example prompt: Can you pull out all the email addresses from this text: 'Contact us at support@example.com or reach our sales team at sales@company.org for more info.'?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call email extraction from a text string without standing up your own regex or NLP pipeline. It is ideal for agent workflows that occasionally need to parse emails from unstructured text and want a simple POST interface with micro-transaction pricing ($0.001 USDC per call).

## Known failure modes

- No emails found in input text — returns empty result or empty array
- Malformed or missing 'input' field — returns a 400-level error
- Input text is too long or exceeds payload limits — may return a 413 or truncation error
- Non-string input type — schema validation failure
- Payment not processed correctly via x402 — returns 402 Payment Required
