## 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 uos-genesis-machine-entity-extractor-4c77dc59 -d '<json body>'
```

Example prompt: Can you extract all the emails, phone numbers, URLs, IP addresses, and dates from this text? 'Contact ada@example.com or call 555-123-4567, visit https://example.com, server is at 192.168.1.1, and the deadline is 2026-08-28.'

## When to prefer this

Choose this endpoint when you need fast, multi-entity extraction across all five entity types (emails, URLs, IPs, dates, phones) in a single call with micropayment billing per use. Ideal for agents that process variable volumes of text and want pay-per-call pricing via Base USDC rather than a subscription.

## Known failure modes

- Missing 'input' field returns a validation error
- Non-string body input may result in empty entity arrays
- Payment failure via x402/USDC returns a 402 Payment Required error
- Malformed JSON body returns a 400 Bad Request
- Rate limiting or Cloudflare Worker timeouts may return 5xx errors

## How this service works

Autonomous paid machine utilities using x402 and Base USDC.

## Output

A JSON object with an 'entities' key containing arrays for each entity type: 'emails', 'urls', 'ipv4', 'dates', and 'phones'. Each array holds zero or more extracted string values found in the input text.
