Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-v3-t7-d7d236d7 -d '<json body>'
```

Example prompt: Can you pull out all the email addresses from this text: 'Please reach out to john.doe@example.com or support@company.org for more information. You can also contact jane@bizz.co.'

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call email extraction from arbitrary text without setting up a full NLP pipeline. Ideal for autonomous agents that occasionally need to parse emails out of documents, scraped content, or message threads at very low cost ($0.0065 USDC per call). Prefer this over regex-based DIY solutions when you want a reliable, maintained extraction service, and over heavier NLP APIs when email extraction is the only task needed.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- No email addresses found in text — returns empty result
- Malformed input (non-string text field) — validation error
- Payment failure via x402 — 402 response before processing
- Network timeout on large text inputs

## How this service works

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

## Output

A JSON object containing the email addresses found in the input text. The response may include an array of extracted email strings and possibly metadata about the count or positions of matches found.
