## 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 bolt-keyword-extraction-3535d0da -d '<json body>'
```

Example prompt: Pull out the top 8 keywords from this article text: 'Artificial intelligence is transforming healthcare by enabling faster diagnosis, personalized treatments, and predictive analytics for patient outcomes.'

## When to prefer this

Use this endpoint when you need fast, pay-per-use keyword extraction without setting up a dedicated NLP pipeline. Ideal for agents that need to tag content, generate SEO metadata, or summarize topics on demand. The x402/USDC micropayment model makes it suitable for low-volume or sporadic usage without subscription overhead.

## Known failure modes

- Missing required 'text' field returns validation error
- Empty string input may return empty keyword list or error
- Very short text may yield fewer keywords than requested via 'count'
- Payment failure via x402 returns 402 status before processing
- Count parameter exceeding available meaningful keywords may return fewer results than requested
