Key features
Multi-Identifier Input
Resolve by CIK, ticker, FIGI, ISIN, CUSIP, or company name. Any identifier in, canonical entity out.
Cross-Identifier Mapping
Get all known identifiers for an entity in one response. Map between CIK, ticker, FIGI, ISIN, and CUSIP.
Exchange & Sector
Every resolved entity includes exchange listing, sector, industry, and SIC code classification.
Alias Resolution
Handle historical tickers, name changes, and identifier transitions without maintaining your own mapping table.
Dated Latency Proof
Entity-resolution latency claims are tied to benchmark methodology, capture date, and checked-in raw artifacts.
Canonical Graph
Issuers, filers, managers, insiders, funds, and aliases connect through a single identity graph.
