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 value (0–100), its classification (e.g. Extreme Fear, Fear, Neutral, Greed, Extreme Greed), its recent trend direction, aggregated news-headline sentiment polarity, and an overall bullish/bearish/neutral composite score — optionally scoped to a specific coin or keyword query.
Example use cases
Pre-trade crypto sentiment check
“Before I make any moves, can you tell me whether the crypto market is in fear or greed territory right now, and whether news sentiment is bullish or bearish overall?”
Coin-specific sentiment for Ethereum
“What's the current market sentiment around Ethereum specifically — combine the Fear and Greed index with how ETH is being covered in the news and give me one clear bullish, bearish, or neutral verdict.”
Daily crypto mood briefing for a newsletter
“I need today's crypto market mood summary — pull the Fear and Greed index value and classification, note whether sentiment is trending up or down, and factor in what the latest headlines are saying.”
Technical details
Endpoint
GEThttps://payai.agentstools.dev/crypto/sentiment-ctlWhen to prefer
Choose this endpoint when you need a single unified crypto sentiment signal that combines both behavioral market data (Fear & Greed index) and news-driven sentiment in one call. Prefer it over raw Fear & Greed APIs when news context matters, or over raw NLP sentiment APIs when you also need the quantitative index. Especially useful for coin-specific sentiment when you want both dimensions without stitching multiple sources together.

- Fear & Greed API (alternative.me) temporarily down — index value may be absent
- Invalid query parameter format — endpoint returns 400 or empty data
