## 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 manylives-me-keyword-extractor-7a701c45 -d '<json body>'
```

Example prompt: Pull out the top 8 keywords from this paragraph and give me a one-line topic for it: 'Small AI agents now pay each other per call for data lookups, safety checks and summaries, settling in a US-dollar stablecoin within seconds.'

## When to prefer this

Choose this endpoint when you need fast, ranked keyword extraction with a topic label from arbitrary free-form text, especially within agent workflows that require lightweight NLP without spinning up a dedicated ML pipeline. Ideal when you need both a topic headline and prioritized key phrases in a single call. At $0.01/call it is cost-effective for high-frequency use cases like content tagging, indexing, or SEO enrichment.

## Known failure modes

- Text exceeds 20,000 character limit — request rejected
- Missing required 'text' field — API returns error
- Very short or low-information text may yield sparse keyword results
- Non-English text may produce lower quality or fewer results depending on model support
- Invalid 'max' value (non-numeric string) may cause unexpected behavior
