Ontology & Fusion

Fusion Response

Fusion parameters, fields, exposure paths, sources, and coverage limits.

GET /api/v2/entities/{entityId}/fusion and the in-app Cyber-market exposure panel return the same view for an organization or vendor entity.

Parameters

ParameterDefaultRangeMeaning
windowDays901–365Days of history ending at request time
adjacencyDays71–90How long after a cyber event a market event counts as adjacent

Response fields

FieldMeaning
entityThe resolved company (after catalog merge redirects)
windowstart, end, and adjacencyDays actually used
counterpartiesUp to 12 parties on the exposure path, with relation, provenance, and, for ledger ties, confidence and verification
identifiersLive designations of ledger subjects anchored to the company
topicsWorkspace topics whose subject is the company or a counterparty, with the path relation
timelineUp to 200 dated events in the window, newest first
undatedEvents without a source time, never placed at a guessed date
summariesPer domain: event count, highest severity, latest event time
adjacenciesUp to 50 cyber → market pairs within adjacencyDays, same-path pairs first
coveragetruncated and plain-language notes on read budgets and source limits

Exposure paths

RelationFrom a catalog relationFrom a ledger claim
supplierThe party supplies the companyThe party's subject supplies the company's subject
customerThe company supplies the partyThe company's subject supplies the party's subject
parentThe company is subsidiary_of the partyThe company's subject is subsidiary-of the party's subject
subsidiaryThe party is subsidiary_of the companyThe party's subject is subsidiary-of the company's subject
operated-systemThe company operates or uses a software, API service, or model entityThe company's subject operates a system subject

A ledger tie wins over a catalog tie to the same entity because it carries evidence and a verification state.

Catalog paths use current resolved relationships. Changing windowDays filters events but does not reconstruct earlier catalog relationships. Ledger paths use claims valid at window.end.

Event sources

DomainSources
cyberRelevant CVEs, threat actors, readable cyber signals, and cyber incidents
marketReadable market signals, workspace financial facts, relevant prediction markets, and economic incidents
supply_chainLedger supply and ownership ties, readable supply-chain signals, maritime incidents, and aviation incidents
geopoliticalReadable geopolitical, military, and policy signals, plus conflict and political incidents

Signals are readable when they are global or community, belong to the key's workspace, or are the caller's own private signals.

Provenance

ValueMeaning
catalogY2's shared catalog: entities, relations, signals, incidents, markets
ledgerYour workspace's entity ledger
workspaceYour workspace's research, such as company financial history

Read budgets

Each source has a read limit.

SourceLimit
Catalog relationships150 in each direction
Cyber relationships per path party10 most recently added affects and 10 targets relationships
Signal subjects per path party15 within the selected window
Financial history12 most recently recorded facts
Anchored ledger subjects5
Workspace topics200
Incidents and prediction markets100 most recently updated records per source
Timeline output200 events
Cyber-market pairs50

Financial facts use their information dates. Ledger ties use valid_from when available. coverage.notes reports source limits. coverage.truncated is true when any source or output limit omits records. A truncated result can therefore contain fewer than 200 events. Sources naming both the company and a counterparty retain the direct company path.
