## 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 24k-labs-entity-extractor-de34c426 -d '<json body>'
```

Example prompt: Can you extract all the URLs, email addresses, and @mentions from this text: 'Check out https://x.io for updates, reach us at ops@x.io, or ping @dev on the forum'?

## When to prefer this

Choose this endpoint when you need a lightweight, fast, multi-entity extraction in a single call that simultaneously returns URLs, emails, and @mentions from freeform text. Prefer it over general-purpose NLP APIs when you want structured JSON output at low cost ($0.002/call) without running a full NLP pipeline. It is ideal for processing scraped web content, social posts, or user-submitted text where contact and link information needs to be structured quickly.

## Known failure modes

- Empty or whitespace-only input returns zero entities with total=0
- Malformed or extremely long text may result in partial extraction or timeout
- Obfuscated emails (e.g. 'user at domain dot com') will not be detected
- URLs lacking a scheme (e.g. 'example.com' without 'https://') may be missed
- Non-standard mention formats may not be captured

## How this service works

A curated directory of x402 services — each one on the list on purpose, with the health, uptime, and independent trust grades from across the ecosystem gathered in one place.

## Output

Returns a JSON object with a total entity count and a nested entities object containing three arrays: urls (all HTTP/HTTPS links found), emails (all RFC-5322-style email addresses found), and mentions (all @handle references found) in the input text.
