LEI Lookup API – GLEIF Legal Entity Identifier Search with Parent Companies

Find any company's Legal Entity Identifier (LEI) by name or LEI code and get its legal name, addresses, registration status, renewal date, BIC codes and direct/ultimate parent from the official GLEIF index – no API key.

Data comes straight from the public GLEIF Global LEI Index (CC0 / public domain) through GLEIF's free API. No API key, no proxy, no scraping of web pages.

LEI lookup use cases: KYB, KYC and CRM enrichment

• Resolve a list of company names to LEIs in one run (search by legal name or full-text).
• Validate and enrich a list of LEI codes (up to 50 codes are batched per API call).
• Filter by country and ACTIVE entities only.
• Resolve direct parent and ultimate parent (consolidation ownership reported to GLEIF).

Input: company names or LEI codes

Field	Description
queries (required)	Company names and/or 20-character LEI codes. LEI codes are detected automatically.
searchMode	legalName (default) or fulltext.
country	Optional ISO-3166 alpha-2 filter, e.g. US.
maxResultsPerQuery	Records per name query (default 5).
includeParents	Also resolve direct / ultimate parent records (default false).
activeOnly	Only return ACTIVE entities.

  "maxResultsPerQuery": 1,
  "country": "US",
  "includeParents": true

LEI lookup pricing (pay per result)

• LEI record returned: $0.002
• Parent resolved (only when includeParents is on and a parent exists): $0.004

You are never charged for queries that return nothing. Set a maximum cost per run in Apify and the Actor stops when it is reached.

Limits and data notes

• Runs are paced at about 1 request/second, under GLEIF's published limit of 60 requests/minute per IP.
• A small share of LEIs report "no known parent" or "non-consolidating"; in that case the parent fields are null.
• Data accuracy depends on what entities self-report to GLEIF. This Actor is not affiliated with or endorsed by GLEIF.

from apify_client import ApifyClient

client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("exprmntl/gleif-lei-lookup").call(run_input={"queries": ["Microsoft Corporation", "HWUPKR0MPOU8FGXBT394"], "includeParents": true})
for item in client.dataset(run["default_dataset_id"]).iterate_items():
    print(item)

Running with no input performs a small demo run with example data.

FAQ

How do I find a company's LEI number? Put the company name in queries. The Actor fuzzy-searches GLEIF legal names and returns matching LEIs with status and address.

Can I look up the parent or ultimate owner of a company? Yes. Set includeParents: true to add the direct and ultimate parent LEI records reported to GLEIF.

Can I check many companies at once? Yes. Pass hundreds of names or LEIs in one run; results come back as one dataset (JSON, CSV, Excel).

Do I need a GLEIF API key? No. GLEIF data is free (CC0); you only pay the per-result Actor fee.

Is this good for KYB onboarding? It verifies legal name, jurisdiction, registration status and LEI renewal – a common first KYB check. It is not a full compliance solution.
