## 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-mentions-extractor-top-10-947ac8f5 -d '<json body>'
```

Example prompt: Can you extract the top 10 most mentioned entities or keywords from this article text? Here's the content: 'Apple announced record profits today as CEO Tim Cook highlighted the company's strong iPhone sales across Asia and Europe...'

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.03 USDC) ranked extraction of the top 10 mentions from a text blob without running your own NLP pipeline. It is ideal for agents that need to summarize key entities from articles, reports, or aggregated content in a single pay-per-call operation with no setup overhead. Prefer this over general LLM summarization when you want a structured, ranked list of mentions specifically.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected or truncated
- Empty or whitespace-only text input — may return empty results or an error
- Payment failure via x402 on Base — 402 response, call not executed
- Malformed JSON body or missing 'text' field — 400 Bad Request
- Ambiguous or very short text — may return low-quality or sparse mention results

## How this service works

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