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
Returns a composite sentiment object including: the Fear & Greed index numeric value, its classification (e.g. Fear, Greed, Extreme Greed), its recent trend direction, aggregated news-headline sentiment polarity, and a final blended bullish/bearish/neutral label for the overall market or a specific coin.
Example use cases
Pre-trade sentiment check for Bitcoin
“Before I make a BTC trade, can you tell me the current market sentiment for Bitcoin? I want to know the Fear and Greed index, whether it's trending up or down, and whether news headlines are bullish or bearish.”
Ethereum sentiment dashboard alert
“Is the market sentiment for Ethereum currently bullish, bearish, or neutral? Give me the blended Fear and Greed plus news-headline score so I can decide whether to rebalance my ETH position.”
General crypto market mood check
“What's the overall mood of the crypto market right now? I want the Fear and Greed index value, its classification, and a composite bullish/bearish/neutral signal based on news headlines too.”
Technical details
Endpoint
GEThttps://payai.agentstools.dev/crypto/sentiment-tagWhen to prefer
Choose this endpoint when you need a single, ready-to-use sentiment signal that combines both the quantitative Fear & Greed index and qualitative news-headline sentiment into one bullish/bearish/neutral classification. Prefer it over raw Fear & Greed APIs when you also want news-driven context, and over pure news-sentiment APIs when you want the quantitative Fear & Greed baseline included. Ideal for trading decision support, portfolio monitoring alerts, or market briefings where a single composite verdict is more useful than two separate signals.
Side effects
- Coin symbol not recognized — returns generic market sentiment instead of coin-specific
- Upstream alternative.me API unavailable — Fear & Greed data may be stale or missing
- No recent news headlines found for queried coin — headline sentiment component may be absent
- Invalid query parameter format — endpoint may return an error or fall back to market-wide defaults
