## 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 primeapi-ai-keyword-extraction-d101f053 -d '<json body>'
```

Example prompt: Extract the most relevant AI-generated keywords from this text: 'Decentralized finance is transforming traditional banking by enabling peer-to-peer lending, borrowing, and trading without intermediaries.'

## When to prefer this

Use this endpoint when you need AI-powered keyword extraction from free-form text or a topic query, especially in a pay-per-call context without API key management. Prefer this over traditional NLP libraries when you want a hosted, on-demand keyword extraction service billed per use via USDC on Base.

## Known failure modes

- Empty or missing query field returns an error or empty keyword list
- Query too long may be truncated or rejected
- Ambiguous or very short queries may yield low-quality or generic keywords
- Payment failure (insufficient USDC) returns 402 Payment Required
- Service unavailability returns 5xx error
