## 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 grokzilla-keyword-extract-8364b243 -d '<json body>'
```

Example prompt: Can you extract the keywords from this paragraph for me: 'Artificial intelligence is transforming industries from healthcare to finance, enabling faster decisions and smarter automation.'

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call keyword extraction microservice that integrates with the x402 crypto micropayment rail and costs only $0.008 USDC per call — ideal for AI agents that need to tag or index text at scale without a monthly subscription.

- Empty or missing input body — may return an empty keyword list or error
