## 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-5cece423 -d '<json body>'
```

Example prompt: Pull out all the email addresses from this block of text for me: 'Contact our team at hello@acme.com or support@acme.com, and reach our CEO at jane.doe@acme.com for partnership inquiries.'

## When to prefer this

Choose this endpoint when you need a cheap, pay-per-call email extraction from raw text without setting up a full NLP pipeline. At $0.01 USDC per call via x402 on Base, it's ideal for agent workflows that occasionally need to parse contact details from scraped or user-supplied text without committing to a subscription.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected or truncated
- No email addresses found — returns empty result
- Malformed or obfuscated emails (e.g. 'user at domain dot com') may not be detected
- Payment failure via x402 prevents endpoint access
- Non-text binary content passed as input produces no useful output

## How this service works

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