## 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 one-engine-email-extractor-1e1c9b7a -d '<json body>'
```

Example prompt: Pull out all the email addresses from this text for me: 'Contact us at support@example.com or reach our sales team at sales@company.org for inquiries.'

## When to prefer this

Choose this endpoint when you need a cheap, fast, pay-per-call way to extract email addresses from unstructured text without setting up your own regex pipeline or NLP infrastructure. At $0.004 USDC per call on Base via x402, it is ideal for autonomous agents that process text sporadically and need a zero-setup, on-demand solution. Prefer alternatives if you need bulk processing with volume discounts or need to extract multiple entity types beyond emails.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected or truncated
- No email addresses present in text — returns empty result
- Malformed or obfuscated emails (e.g. 'user at domain dot com') may not be detected
- Payment failure via x402 protocol results in 402 response before processing
- Ambiguous email-like strings may produce false positives

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output
