How this service works
Real-time crypto market news with sentiment analysis and top headlines ranked by importance, for $0.01 per call. One request, no parameters needed — get the latest market-moving stories as structured JSON, ready for trading agents and research pipelines. Relayed live from a proven upstream source; if the source is down you get a 503 and pay nothing. Pay per call in USDC on Base — no account, no API key.
Output
A structured JSON object containing ranked crypto news headlines, each annotated with sentiment (positive/negative/neutral or scored), importance ranking, and story metadata — ready for consumption by trading agents or research pipelines. Returns a 503 with no charge if the upstream news source is unavailable.
