## 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-83660b7b -d '<json body>'
```

Example prompt: Extract all email addresses from this text for me: 'Contact our team at support@example.com or reach John at john.doe@company.org for billing questions.'

## When to prefer this

Choose this endpoint when you need a cheap, fast, pay-per-call email extraction from raw text without managing your own regex or NLP pipeline. At $0.0005 USDC per call it is ideal for high-volume agentic workflows on Base using x402. Prefer it over general-purpose LLM extraction when you want a deterministic, structured output and cost predictability.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected or truncated
- No email addresses present in the text — empty result returned
- Malformed or non-string input — schema validation error
- Payment failure via x402 on Base — 402 response with payment details
- Obfuscated emails (e.g. 'user at domain dot com') may not be detected

## How this service works

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

## Output

Returns a JSON object containing the email addresses extracted from the submitted text. The exact response structure uses additionalProperties, so the agent should expect a list or array of found email addresses, potentially with metadata about each match.
