How this service works
Get a paginated crypto news feed with per-asset sentiment signals.

A paginated list of crypto news articles, each containing the article URL, title, publication timestamp, associated crypto assets (with name, slug, symbol), source details (name and type), and per-asset sentiment scores ranging from -1 to +1.

Example use cases
Monitor Bitcoin sentiment across major news outlets

Build a daily briefing for portfolio assets
“Get me the newest crypto news for Ethereum and Solana with sentiment scores, paginated so I can see the top 20 articles. I want to understand if there's any major positive or negative momentum around my holdings.”
