Event significance is a family-scoped weighted blend, renormalized so every event family spans a true 0-1: each event's raw total is divided by the maximum its own family can reach (Conflict 1.00, CAMEO+ POLITICAL 0.90, other CAMEO+ domains 0.65). All events: Goldstein severity 0.25, article evidence 0.05, confidence 0.05. Conflict only: fatalities 0.55 (log-scaled by body count) and civilian targeting 0.10. CAMEO+ only: magnitude 0.20, systemic importance 0.15, propagation potential 0.10, market sensitivity 0.10. When magnitude is unmeasured its term AND its 0.20 weight are both dropped. The four CAMEO+ metrics are rubric scores produced by published formulas - ordinal ranking signals, not measurements, probabilities, or predicted price moves. goldstein_scale is one canonical public metric, populated for Conflict Events and CAMEO+ POLITICAL Events where meaningful. Story linked_event_count is a Story-to-Event link aggregate, not a distinct Event total. servers: - url: https://gdeltcloud.com description: Production - url: http://localhost:3000 description: Local development security: - ApiKeyAuth: [] tags: - name: Events description: Coded CAMEO+ / conflict events — search, fetch, and summarize. - name: Stories description: Clustered narratives (stories) and their articles. - name: Entities description: >- People & organizations — resolve a name to an entity, then fetch its profile and tone. - name: Geography description: Admin-1 geography lookups. - name: Energy description: Global Energy Monitor assets + ownership registry. - name: Facilities description: >- Unified physical-asset directory — GEM energy assets + World Port Index ports + Epoch AI data centers on one keyed surface, resolved to spine owners.
