# ONE Engine Email Extractor (T5)

> ONE Engine Email Extractor (T5) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0025/call, status unknown (last checked 2026-10-02).

Extracts email addresses from a block of text up to 50,000 characters using a pay-per-call API on Base via x402.

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-t5-e755b809 -d '<json body>'
```

Example prompt: Can you pull out all the email addresses from this text I'm pasting in? Here it is: 'Contact our team at support@example.com or sales@company.org for more information. Press inquiries: press@example.com.'

## When to prefer this

Choose this endpoint when you need a cheap, low-latency, pay-per-call solution to extract email addresses from arbitrary text without setting up a full NLP pipeline. Ideal for autonomous agents that occasionally need to parse contacts from scraped or pasted text, where the $0.0025 per-call cost is preferable to running a self-hosted regex or ML extraction service.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected or truncated
- No email addresses present in text — returns empty result
- Malformed input (non-string text field) — schema validation error
- Payment failure via x402 — 402 response before processing
- Rate limiting or worker timeout on very dense text

## How this service works

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