## When to prefer this

Choose this endpoint when an AI agent needs to retrieve real-world news articles by keyword search, especially when a pay-per-call micropayment model is acceptable and the agent operates in a Web3-native or x402-compatible environment. Prefer this over general web search when structured news data with timespan filtering is needed.

## Known failure modes

- Missing required 'q' parameter returns an error
- Invalid or unrecognized timespan format may return empty results or an error
- No matching articles found returns empty results set
- Payment failure via x402 protocol prevents the call from executing
- Rate limiting or quota exhaustion returns a 402 or 429 error
