How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
A JSON object containing a count of matching articles and an array of news articles, each tagged with AI-generated sentiment (positive/neutral/negative), one or more coin labels, and a category from the 11-class taxonomy (regulation, DeFi, AI, macro, hack, NFT, stablecoin, layer2, ETF, exchange, etc.).
Example use cases
Monitor DeFi exploit news alerts
“Check for any hack or exploit news in the DeFi space from the last 12 hours — I want to know if any protocols have been hit and whether sentiment is tanking so I can adjust my positions before things get worse.”
Track ETF approval sentiment shifts
“Pull the most recent ETF-related crypto news and show me the sentiment breakdown — I'm trying to gauge whether market mood around a Bitcoin spot ETF is turning positive or negative heading into the end of the week.”
Detect narrative trends across coins
“Give me a broad sweep of crypto news from the last 48 hours across all coins, grouped by category, and flag anything with strong positive sentiment — I want to spot which narratives are gaining momentum right now, whether that's layer2, stablecoins, or macro tailwinds.”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/newsWhen to prefer
Use this endpoint when you need AI-classified, sentiment-tagged crypto news aggregated across sources, especially for event-driven trading workflows, narrative detection, or monitoring specific coins or categories like hacks, regulation, or DeFi. Prefer this over generic news APIs when you need structured coin tagging and the 11-category taxonomy already applied.
