## 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-8fb19f31 -d '<json body>'
```

Example prompt: Search for the latest crypto news about Ethereum layer-2 scaling in English and give me a summary of what's happening.

## When to prefer this

Choose this endpoint when an agent needs to search for cryptocurrency or blockchain news by keyword or topic, especially within an x402 micropayment-enabled workflow. It is well-suited for real-time news retrieval tasks where the agent is operating in a pay-per-call model and needs fresh, query-specific crypto journalism rather than price data or on-chain metrics.

## Known failure modes

- Missing required `query` field returns a validation error
- Payment not fulfilled results in HTTP 402 response blocking access
- Upstream news API unavailable causes empty or error response
- Invalid language code may return no results or default to a fallback language
- Very niche or misspelled query terms may return zero results
