## 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-3bc62a3c -d '<json body>'
```

Example prompt: Can you pull out all the email addresses from this text for me: 'Please reach out to john.doe@example.com or support@company.org for assistance, or CC legal@firm.net'?

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.001 USDC) microservice call to extract email addresses from arbitrary text without setting up your own regex or NLP pipeline. Ideal for agents processing scraped content, documents, or user-submitted strings where contact email harvesting is needed on demand.

## Known failure modes

- No emails found in input — returns empty list or empty result
- Malformed or non-string input causes validation error
- Obfuscated emails (e.g. 'user [at] domain [dot] com') may not be detected
- Very large input strings may time out or be truncated
- Payment failure via x402 results in 402 response before processing
