Output
Returns a composite sentiment object including the Fear & Greed index numeric value, its classification (e.g. Extreme Fear, Fear, Neutral, Greed, Extreme Greed), a trend direction, aggregated news-headline sentiment score, and a final blended bullish/bearish/neutral classification — optionally scoped to a specific coin or query.

Endpoint
GEThttps://payai.agentstools.dev/crypto/sentiment-nmWhen to prefer
Choose this endpoint when you need a single blended crypto sentiment signal that combines both the established Fear & Greed index and real-time news sentiment in one call, especially when you want coin-specific sentiment rather than general market mood. Prefer it over raw Fear & Greed APIs when news context matters, or over pure NLP sentiment tools when you also want the quantitative Fear & Greed dimension.
Side effects
- No coin match found if an unrecognized ticker is supplied
- Upstream alternative.me API unavailable causing stale or missing Fear & Greed data
- RSS feed unavailable resulting in news sentiment component being absent
- Rate limiting or payment failure (x402) returning 402 status
- Empty or noisy results if query string is too broad or ambiguous
