## 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-t2-019e068f -d '<json body>'
```

Example prompt: Can you extract all the mentions from this article text for me? Here's the content: 'Apple CEO Tim Cook met with Elon Musk at the OpenAI summit in San Francisco last Tuesday to discuss AI regulation...'

## When to prefer this

Choose this endpoint when you need a cheap, low-latency, per-call mention extraction from a text block up to 50,000 characters and are operating in an autonomous agent pipeline using x402 micropayments on Base. It is ideal for high-volume text processing workflows where cost efficiency matters and you need raw mention extraction without a full NLP pipeline.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected or truncated
- Empty or missing 'text' field — validation error returned
- Payment failure via x402 protocol — 402 response, call not executed
- Ambiguous or very short text may yield few or no mentions
- Non-English text may result in lower extraction accuracy or empty results

## 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 in the input text. The exact structure may vary (additionalProperties: true), but typically includes a list of identified mentions such as named entities, references, or tagged items detected within the provided text.
