How this service works
SYNTHORA gdelt-tension: geopolitical tension index for any topic/country — news-mention spike vs 7d baseline, average tone shift, escalation flag and the headlines causing it. The early signal for Polymarket geopolitical markets (high variance, high spread). Source: GDELT DOC 2.0 (100+ languages, free, no key), 6h-prefetched cache for reliability.
Output
Returns a geopolitical tension index object including: the ratio of current news mentions vs the 7-day rolling baseline (mention spike), the average media tone shift, a boolean escalation flag indicating abnormal activity, and a list of headlines responsible for the signal. Data is sourced from GDELT DOC 2.0 covering 100+ languages and served from a 6-hour prefetched cache for reliability.
Example use cases
Polymarket geopolitical market signal
“I'm trading on Polymarket and want an early signal for the 'Israel-Iran conflict escalates' market — can you get the current GDELT tension index for Israel-Iran, including the escalation flag and the headlines causing any spike?”
Geopolitical risk briefing for a country
“Give me a geopolitical tension report for Venezuela right now — I need the news-mention spike compared to last week's baseline, the average tone shift, and whether there's an escalation flag.”
Topic-specific tension monitoring
“Is there any unusual tension signal around 'Taiwan Strait' in the global news right now? Check the GDELT tension index and tell me if there's an escalation flag and what headlines are driving it.”
Technical details
Endpoint
POSThttps://api.hergertsynthora.com/v1/gdelt-tensionWhen to prefer
Choose this endpoint when you need a fast, aggregated geopolitical tension signal derived from global news at scale — especially for prediction market trading signals, geopolitical risk briefings, or escalation early-warning systems. It is preferable over manual news scraping or sentiment APIs because it combines mention-volume anomaly detection with tone analysis and escalation flagging in a single call, backed by GDELT's 100+ language corpus with a cached response for reliability. Not ideal for real-time breaking news within the past 6 hours due to cache lag.
Side effects
- Topic or country string too vague to match GDELT entities — returns low-confidence or empty result
- GDELT cache stale beyond 6-hour refresh window — data may lag real-time events
- Ambiguous topic string matching multiple unrelated events — mixed/noisy tension scores
- Service unavailable if GDELT upstream is unreachable and cache is expired
- No headlines returned if topic has very low global news volume
