## 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 hermes-micro-agent-keywords-extraction-d4fabd2a -d '<json body>'
```

Example prompt: Extract the main keywords from this paragraph for me: 'Blockchain technology is transforming financial services by enabling trustless, decentralized transactions without intermediaries, reducing costs and increasing transparency.'

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-use keyword extraction call billed in USDC on-chain with no subscription required. Ideal for agents that need occasional NLP micro-tasks without committing to a full NLP platform. Particularly suited for x402-aware agents that can handle HTTP 402 payment flows natively.

## Known failure modes

- Missing or empty prompt field returns an error
- Payment not verified on Base blockchain results in HTTP 402 rejection
- Malformed JSON body causes a 400 Bad Request
- Very short or nonsensical input may return few or no meaningful keywords
- Network timeout if the micro-agent host is unavailable
