How this service works
Real-time crowd sentiment oracle for any topic or asset: GDELT global-news tone timeline -> sentiment (very_bullish..very_bearish), tone score, trend and trading signal, with top headlines. POST {"query":"bitcoin","timespan":"6h"}. Deterministic, Ed25519-signed. SYNTHORA.
Output
Returns a sentiment classification label (e.g. very_bullish, bearish), a numeric tone score, a trend direction indicator, a trading signal, and a list of top news headlines that contributed to the analysis — all cryptographically signed with Ed25519 for verifiability.
Example use cases
Crypto trading sentiment check
“What's the sentiment on Ethereum right now based on the last 24 hours of global news — is it bullish or bearish, and what's the trading signal?”
Macro topic news tone analysis
“How is global news sentiment trending around inflation over the past 48 hours? Give me a tone score and the top headlines driving it.”
Equity asset sentiment monitoring
“Check the crowd sentiment for NVIDIA stock over the last 12 hours — I want to know if it's bullish or bearish and what the trend looks like.”
Technical details
Endpoint
POSThttps://api.hergertsynthora.com/v1/sentimentWhen to prefer
Choose this endpoint when you need a fast, verifiable, news-driven sentiment signal for any asset or topic — especially for trading or market-intelligence workflows where you want a structured bullish/bearish classification with a cryptographically signed result. Prefer it over social-media sentiment tools when you need global news tone rather than Twitter/Reddit chatter, or when auditability via Ed25519 signatures matters.
Side effects
- Unsupported or too-generic query term yields low-confidence or neutral results
- Timespan too short (1h) may return sparse data and unreliable signal
- Payment not included or insufficient USDC triggers 402 error
- GDELT data lag may affect freshness at the very short end of the timespan range
- Invalid timespan enum value returns validation error
