How this service works
Resolve companies, legal entities and financial reference data using authoritative sources. Machine-native, pay per request, no subscription.
Output
Returns a JSON object with a `data` field containing the entity's LEI relationships (direct parent, ultimate parent, children) as sourced live from the GLEIF API, along with `success` and `complete` flags, any `warnings`, and provenance metadata indicating the GLEIF source, CC0 1.0 license, and live freshness.
Example use cases
Corporate ownership due diligence
“I need to know who the direct and ultimate parent companies are for the entity with LEI 549300MLUDYVRQOOXS22 — can you fetch the relationship data from the LEI registry?”
Counterparty risk analysis
“We're onboarding a new counterparty whose LEI is 5493006QMFDDMYWIAM13. Can you pull their LEI relationship records so I can see their ownership chain?”
Regulatory reporting hierarchy mapping
“For our EMIR reporting, I need the full corporate relationship structure for LEI 5299009KDSUYQ0LKBF60 — please look up the parent and ultimate parent relationships.”
Technical details
Endpoint
GEThttps://www.celerapi.com/v1/lei/%7Blei%7D/relationshipsWhen to prefer
Use this endpoint when you need live, structured LEI relationship data (parent/child/ultimate parent) for a specific legal entity and want to avoid building a GLEIF API integration yourself. Ideal for compliance, KYC, counterparty risk, or regulatory reporting workflows where corporate ownership hierarchy is needed and freshness matters. Prefer over direct GLEIF API calls when you need pay-per-request access without API key management.
Side effects
- Invalid or malformed LEI code returns an error or empty data
- LEI not found in GLEIF registry returns empty relationships
- Network or GLEIF upstream outage causes delayed or failed response
- Relationship data incomplete when GLEIF source is partially available (reflected in warnings array)
- Payment failure (HTTP 402) if USDC payment is not included or is insufficient
