## 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 x402-deployer-x402-deployer-workers-dev-c276d6d1 -d '<json body>'
```

Example prompt: Extract all named entities from this text — I need people, organizations, locations, dates, phone numbers, emails, URLs, and any monetary amounts: 'On March 5, 2024, CEO Jane Smith of Acme Corp signed a $2.5M deal with Global Industries Ltd. Reach her at jane.smith@acme.com or +1-555-234-5678.'

## When to prefer this

Use this endpoint when you need to extract multiple entity types (people, orgs, locations, dates, emails, URLs, phones, money) from freeform text in one call, particularly when you want Mistral LLM quality over simpler regex or rule-based approaches. Prefer this over generic LLM calls when you want structured, typed entity output without prompt engineering.

## Known failure modes

- Empty or whitespace-only input text returns no entities
- Very long documents may be truncated or exceed model context limits
- Ambiguous entities (e.g. 'Apple' as fruit vs company) may be misclassified
- Non-English text may yield lower accuracy or missed entities
- Malformed input returns a 400 or error response
- Payment failure returns 402 Payment Required
