How this service works
Composite crypto market sentiment: the Fear & Greed index (value, classification, trend) blended with aggregated news-headline sentiment into one bullish/bearish/neutral score, optionally focused on a coin or query. Data by alternative.me (attributed) + curated RSS headlines.
Output
A composite sentiment object including the Fear & Greed index value and classification (e.g. 'Extreme Fear', 'Greed'), its trend direction, aggregated news headline sentiment scores, and a single combined bullish/bearish/neutral label — optionally scoped to a specific coin or query filter.
Example use cases
Example prompt
“What's the current overall crypto market sentiment — give me the Fear & Greed index blended with news headline sentiment, and break it down specifically for ETH.”

Endpoint
GEThttps://api.agentstools.dev/crypto/sentimentWhen to prefer
Use this endpoint when you need a single, synthesized sentiment signal combining both the well-known Fear & Greed index and real-time news headline sentiment into one score — especially when you want a quick bullish/bearish/neutral read on the overall crypto market or a specific coin without having to aggregate multiple data sources yourself.
Side effects
- Invalid or unrecognized coin ticker returns empty or generic market-wide result
- Upstream alternative.me API unavailable causes Fear & Greed component to fail
- RSS feed parsing errors may degrade news sentiment component
- No matching news headlines for a very specific query may return neutral sentiment by default
- Rate limiting or payment failure returns 402 Payment Required
