How this service works
Resolve a legal entity across identifier systems. Give exactly one of name, lei, cik, or ticker and get the others back: LEI (GLEIF), SEC CIK, ticker(s) with exchange, jurisdiction, and a canonical entity name. This is the COMPANY-ENTITY resolver: it joins the legal entity (LEI) to its SEC filer identity (CIK/ticker) and back. For SECURITIES (FIGI, ISIN, share-class identifiers) use finance.security-resolve instead -- this one deliberately stays at the legal-entity layer. Composes SEC company_tickers_exchange (public domain) + GLEIF (CC0). The SEC<->GLEIF link is by name-match when you anchor on ticker/cik (best-effort, flagged via bridge + leiName); a supplied LEI is authoritative. Per-source status is returned so a partial resolve is explicit. No CUSIP/SEDOL.
Output
Returns a resolved entity object containing: LEI (from GLEIF), SEC CIK, ticker(s) with exchange, jurisdiction, canonical entity name, a bridge flag and leiName when the SEC-GLEIF link was established by name-match (best-effort), and per-source status codes indicating which lookups succeeded or partially resolved.
Example use cases
Example prompt
“What's the LEI and SEC CIK for Tesla? I have their ticker symbol TSLA and need to cross-reference their GLEIF and SEC identities.”
Technical details
Endpoint
GEThttps://2s.io/api/business/id-resolveWhen to prefer
Use this endpoint when you need to cross-reference legal entity identifiers (LEI, CIK, ticker) for a publicly traded or SEC-registered company. Prefer this over general company search when you specifically need to join GLEIF and SEC identities. Do NOT use for resolving securities-level identifiers like FIGI, ISIN, CUSIP, or SEDOL — those belong to a securities resolver. Best when you have one anchor identifier and need the others for compliance, data enrichment, or cross-database joins.
Side effects
- No match found for the supplied name — GLEIF name search may return empty if name doesn't closely match canonical GLEIF name
- Ambiguous name match returns multiple candidates or incorrect entity
- SEC-GLEIF bridge is best-effort when anchoring on ticker/CIK — leiName may differ from SEC name
- Supplied LEI not found in GLEIF registry
- CIK not found in SEC company_tickers_exchange dataset
- Partial resolve: one source returns data while the other does not, indicated by per-source status fields
- Invalid input — must supply exactly one of name, lei, cik, or ticker
