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: Situations description: >- One real-world occurrence as the Stories and coded Events that belong to it — stored, adjudicated membership (`meta.situation_source: curated`) or a walked neighbourhood around a Story. Discovery, detail, four independently paged member lists, and the only write on the core surface (5 QU with an Idempotency-Key). - name: Entities description: >- People & organizations — resolve a name to an entity, then fetch its profile and tone. Also the publication activity journal (/api/v2/activity): observed evidence of what was published about identities and records — committed batches only, cursor-paged, never source intake. - 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. This is the resolver the rest of the API assumes you called first. - name: Media Intelligence description: >- Press-coverage tone over time and share of voice against a peer set. Requires the `can_use_tone` / `can_use_share_of_voice` entitlement; social signal is an admin-only preview. - name: Facilities description: >- Unified physical-asset directory — GEM energy assets, World Port Index ports and Epoch AI data centers on one keyed surface, resolved to spine owners. Requires the `can_use_facilities` entitlement. - name: Monitors description: >- Organization-shared scheduled checks over the Core API, with email and signed-webhook delivery. Monitor execution does not consume query units. - name: Geography description: >- Country context and admin-1 geography: /api/v2/countries (publication activity, reporting counts, dated economic and resource fundamentals, facility and office inventories, directory mode over every registered country) and admin-1 lookups. - name: Government description: >- US federal awards (USAspending) and foreign-influence registrations (DOJ NSD FARA), resolved onto the entity spine. Requires the `can_use_gov` entitlement. - name: Political Offices description: >- Public political offices and who holds them — legislatures, cabinets, heads of state, courts and IGO posts, with the office start/end dates the publisher states (valid time), resolved onto the entity spine. Actor context for geopolitical analysis; NOT a PEP or sanctions-screening tool. Requires the `can_use_offices` entitlement. - name: Filings description: >- SEC EDGAR filings, XBRL financials, and relations extracted from filing text. Requires the `can_use_filings` entitlement. - name: Reference Data description: >- The GLEIF Global LEI Index — legal-entity reference data, consolidation relationships, and LEI↔ISIN mappings. Requires the `can_use_gleif` entitlement. - name: Energy description: Global Energy Monitor assets + ownership registry. - name: AI Compute description: >- Epoch AI datasets — models, hardware, data centers, companies and chip sales. Requires the `can_use_epoch_ai` entitlement. - name: Macro Finance description: >- FRED economic time series — catalog, point-in-time observations and releases. Requires the `can_use_macro` entitlement. - name: Screening and Reference description: >- Restricted-party lists, name screening and ownership-chain exposure. Requires the `can_use_screening` / `can_use_exposure` entitlement. Analytical coverage, not an audit-grade compliance control. - name: China description: >- China overseas development finance (AidData GCDF). Requires the `can_use_china` entitlement. - name: Maritime description: >- AIS-derived vessel flow — chokepoint transits, last-known vessel positions, carriers, dwell and AIS-dark gaps. Terrestrial AIS only, so coverage thins in open ocean. Requires the `can_use_maritime` entitlement. - name: Atlas Intelligence description: >- Geopolitical-risk and posture indices computed from GDELT Cloud’s own coded events, normalized to each place’s own frozen baseline. - name: Natural Resources description: >- USGS mineral production, reserves and qualified country statistics, composed with the physical Facilities inventory. - name: Briefs description: Source-backed monitoring briefs. - name: Meta description: >- Machine-readable discovery: the value vocabularies, the endpoint contracts, and the query-unit cost model.
