## 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 one-engine-text-mention-extractor-t6-313cc89d -d '<json body>'
```

Example prompt: Scan this 2,000-word article and pull out every mention — people, organizations, places, or any other notable references — so I can see what entities appear in the text.

## When to prefer this

Choose this endpoint when you need a low-cost, pay-per-call mention extraction from arbitrary text without committing to a subscription NLP service. Best suited for agent workflows on Base that already use x402 micropayments and need lightweight entity detection at $0.004 per call.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected or truncated
- Empty or missing 'text' field — validation error
- Payment failure via x402 — 402 response returned before processing
- Malformed request body — 400 bad request
- No mentions found in text — empty results object returned

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

A JSON object containing the extracted mentions found within the input text, likely including the mention strings and their context or positions within the document.
