## 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 agentshelf-email-extractor-1eeadce0 -d '<json body>'
```

Example prompt: Can you pull all the public email addresses from https://example.com/contact and give me a deduplicated list?

## When to prefer this

Use this endpoint when you need to reliably extract real, explicitly present email addresses from a webpage or HTML blob without guessing or hallucinating. Prefer the free sandbox endpoint (POST /v1/sandbox/extract-emails) for testing. Choose this paid endpoint when operating in production and needing guaranteed deduplication and a cap of 100 emails per call.

## Known failure modes

- URL is unreachable or returns a non-200 response — extraction fails with an error
- HTML input exceeds 200,000 character limit — request rejected
- URL string is malformed or under 8 characters — validation error
- Page contains no publicly visible email addresses — returns empty list
- SSRF-safe filtering may block internal/private URLs

## How this service works

Call when an agent needs public emails extracted from a page URL or HTML (de-duped, cap 100). No guessing. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/extract-emails first.

## Output

A deduplicated list of up to 100 publicly visible email addresses found on the given page URL or within the provided HTML, with no guessing or inference — only addresses explicitly present in the content.
