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 containing the Fear & Greed index value, its classification (e.g. Extreme Fear, Greed), its trend direction, aggregated news headline sentiment, and a final blended bullish/bearish/neutral tag — optionally scoped to a specific coin or query.
Example use cases

Technical details
Endpoint
GEThttps://api.agentstools.dev/crypto/sentiment-tagWhen to prefer
Choose this endpoint when you need a single, opinionated sentiment classification that combines both quantitative market fear/greed signals and qualitative news sentiment in one call. Prefer this over raw Fear & Greed-only endpoints (like timing-fng) when you want news headlines factored in. Use it when building trading signals, daily briefings, or market mood dashboards that need a blended bullish/bearish/neutral label rather than raw index numbers alone.
