## 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 machine-shop-extract-typed-patterns-ba01d76e -d '<json body>'
```

Example prompt: Can you pull out all the email addresses, dates, dollar amounts, and Ethereum wallet addresses from this document: 'Invoice date: 2026-10-18, send payment of $450 to me@example.com, wallet: 0xAbC123...'?

## When to prefer this

Choose this endpoint when you need fast, typed structured extraction of specific entity categories (emails, dates, URLs, money, EVM addresses) from a known text block you already have. It is not a web search or live scraping tool — the text must be supplied directly. Prefer it over general-purpose LLM extraction when you want consistent JSON schema output and cost-predictable per-call pricing at $0.004 USDC.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- Malformed or missing 'text' field — validation error
- No entities of any type found — all arrays returned empty
- Ambiguous date formats may be missed or misclassified
- Partial EVM addresses or checksummed variants may not be detected

## Output

A JSON object with five typed arrays: urls (list of URLs found), dates (ISO date strings found), money (monetary values found), emails (email addresses found), and evm_addresses (Ethereum/EVM wallet addresses found). Empty arrays are returned for entity types not present in the input.
