## When to prefer this

Choose this endpoint when you need real-time, ranked, sentiment-annotated crypto news in a single zero-configuration call — no API key or account required, pay-per-use at $0.01 USDC on Base. Ideal for trading agents, research pipelines, or any workflow needing structured market news without managing a news API subscription. Prefer over direct news APIs when you want pay-per-call economics and built-in sentiment ranking without additional processing.

## Known failure modes

- 503 Service Unavailable — upstream news source is down; no charge applied
- Payment failure — USDC payment on Base not confirmed; request rejected
- Malformed request body — POST body must conform to the relay input schema
- Unexpected upstream data format — relay may return inconsistent structure if upstream schema changes
