Not metered. ## OpenAPI ````yaml /api-reference/openapi-v2.json get /api/v2/meta/query-units openapi: 3.0.3 info: title: GDELT Cloud API v2 version: 2.0.0 description: >- Clean v2 REST API for generated GDELT Cloud structured Events, clustered Stories, linked Entities, summaries, admin1 discovery, significance ranking, and paginated article evidence. 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: Unified Search description: >- One fuzzy lookup across every id-space — start here with a name, take the entity id, then reuse it on every other surface.
