## 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-478d6d17 -d '<json body>'
```

Example prompt: Can you pull out all the email addresses from this text for me: 'Please reach out to john.doe@example.com or support@company.org for assistance. CC billing@company.org on all invoices.'

## When to prefer this

Use this endpoint when you need a cheap, fast, pay-per-call extraction of email addresses from raw text without setting up a heavier NLP pipeline. Ideal for autonomous agent workflows on Base that need lightweight contact parsing billed in USDC micro-payments via x402.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- No email addresses found in text — returns empty result
- Malformed JSON input — error response
- Payment failure via x402 — 402 response before processing

## 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 extracted from the input text, likely as an array or list of email strings found within the provided content.
