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-text-f5e11c75 -d '<json body>'
```

Example prompt: Can you pull out all the email addresses from this block of text for me? Here's the content: 'Please reach out to sales@acme.com or support@acme.com, and CC john.doe@partner.org for escalations.'

## When to prefer this

Choose this endpoint when you need a cheap, stateless, pay-per-call extraction of email addresses from raw or unstructured text without setting up any infrastructure. At $0.018 USDC per call it is ideal for agent workflows that sporadically need email parsing without committing to a subscription-based NLP or regex service.

## Known failure modes

- Text exceeds 50,000 character limit — request will be rejected or truncated
- No email addresses present in input — returns empty result
- Malformed or obfuscated emails (e.g. 'user at domain dot com') may not be detected
- Payment failure via x402 on Base — call not executed
- Non-string or missing 'text' field — schema validation error

## How this service works

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

## Output
