## When to prefer this

Choose this endpoint when you need to search cryptocurrency-specific news by keyword and are operating in an x402 micropayment environment. It is well-suited for AI agents that need on-demand crypto news lookups without a subscription, paying only per query (~$0.056 USDC). Prefer this over general web search when you need structured news data scoped specifically to the crypto domain.

## Known failure modes

- Missing required 'query' parameter returns a validation error
- Payment not provided or insufficient USDC causes a 402 Payment Required response
- Invalid language code may return no results or an error from the upstream API
- Upstream news API unavailability causes failure or empty data response
- Overly broad or ambiguous queries may return low-relevance results
