## 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 x402-crypto-news-search-api-ae0e4ceb -d '<json body>'
```

Example prompt: Can you search for the latest English-language crypto news about Bitcoin ETF approvals?

## When to prefer this

Use this endpoint when an agent needs to search for cryptocurrency-related news articles by keyword or topic, especially when a pay-per-use model is acceptable and the query is ad-hoc rather than requiring a standing subscription. Prefer this over general web search when focused, structured crypto news results are needed.

## Known failure modes

- Invalid or missing 'query' parameter returns an error
- Payment not processed correctly via x402 results in 402 Payment Required response
- Upstream news API unavailable causes empty or error response
- Unsupported language code may return no results or an error
- Very broad or ambiguous queries may return loosely related or irrelevant articles
