How this service works
Real-time aggregated cryptocurrency news feed with lexicon-based sentiment analysis and cross-outlet story clustering. Filters by topic, time-range, and sentiment bands.
Output
A list of up to 50 aggregated crypto news articles, each with a sentiment score between -1 and 1, publication timestamp, source outlet, and story cluster grouping. Results are filtered by the requested topic keywords, time range, and sentiment band.
Example use cases
Monitor sentiment shifts in altcoin markets
“Track the sentiment of news about Solana and Polygon over the last 24 hours — show me both the bullish and bearish articles so I can understand what's driving price movements.”
Alert on negative crypto news clusters
“Find all the negative sentiment cryptocurrency stories from today grouped by topic, so I can see what problems the industry is facing and which coins are getting bad press.”
Identify emerging bullish narratives
“Give me the most recent crypto news articles with positive sentiment from the past 12 hours, clustered by story, so I can spot which narratives are gaining traction in the market.”
Technical details
Endpoint
GEThttps://vibesprings.net/api/news/cryptoWhen to prefer
Choose this endpoint when you need real-time cryptocurrency news with sentiment scoring baked in, especially when you want to filter by mood (bullish/bearish) or cluster related stories across multiple outlets. Prefer it over generic news APIs when crypto-specific topic filtering and sentiment bands are required in a single call.

- limit exceeding 50 returns a 400 error
- No articles matching the filters returns an empty result set
- Payment failure (x402) returns a 402 response requiring valid USDC payment
- Topic keyword with no matching articles returns empty array
