LEI Lookup API — Legal Entity Identifier Data
The LEI is the one company identifier that means the same thing everywhere. Twenty characters, issued under a global system, pointing at exactly one legal entity in any jurisdiction — which is precisely what national registration numbers do not do.
- You send
- A 20-character LEI code
- You get back
- Registration details, addresses, status, renewal date and parent links
- Coverage
- Worldwide — entities on the global LEI system.
- Price
- 5 pts — $5 per 1,000
- Charged only when the record resolves. A lookup that finds nothing is not billed.
Ways to get this data
Three approaches teams use today, and where each one runs into trouble.
| Approach | What it takes | Cost | Trade-off |
|---|---|---|---|
| the global LEI system directly | Query the global index and map its record shape yourself | Usually free, sometimes per-document | A different interface, language and data shape for every country you add |
| Collecting it yourself | Build and host a crawler per register, then keep each one alive | Infrastructure and maintenance | Registers change their pages without warning, and nobody is on the hook when yours breaks |
| NeuralVerge | One request, the same shape as every other source in the catalog | $5 per 1,000, misses not billed | Covers Worldwide — other countries are separate sources with the same request format |
What you get back
Every field the response returns.
| Field | Type | Description |
|---|---|---|
lei | string | The 20-character identifier. |
legal_name | string | Registered legal name of the entity. |
legal_address | object | Registered legal address. |
headquarters_address | object | Headquarters address, where it differs. |
registration_authority | object | The national authority the entity is registered with. |
legal_jurisdiction | string | Jurisdiction the entity is formed under. |
entity_category | string | Category assigned to the entity. |
entity_status | string | Whether the entity itself is active. |
initial_registration_date | string | When the identifier was first issued. |
last_update_date | string | When the record was last updated. |
next_renewal_date | string | When the registration must next be renewed — a lapsed record is a signal. |
relationships | array | Parent relationships, each with the parent's identifier and name. |
Every source answers in the same shape: a session id, a readable human summary, a structured machine object and the points the call consumed. Learn it once and it holds across every source in the catalog.
How to run it
The same lookup works from the app, the API, or as a tool an agent can call mid-task.
A JSON schema passed as extract_schema_json pins the response shape, which is why one endpoint serves every register in the catalog — only the URL and the schema change. The Get API Code button in the app hands you the complete command with the schema already filled in.

}'What teams use it for
Where this field shows up in an actual workflow.
Use one identifier instead of reconciling a different number per country.
Anchor a counterparty record to an identifier that regulators recognise.
Collapse the same legal entity recorded under several local names.
Attach the identifier that financial reporting regimes ask for.
Coverage, freshness and limits
What this source covers, how fresh it is, and where it stops.
Worldwide — entities on the global LEI system.
Read at request time, so the answer reflects the register as it stands when you ask.
the global LEI system is a public register. Every response carries the source URL it was read from and a session id you can trace.
- —Only entities that have obtained an LEI resolve here, and most small companies have not.
- —An identifier can lapse. The record carries both the entity status and the next renewal date, and a lapsed registration is itself a signal.
- —It identifies the legal entity, not its trading names or brands.
Questions, answered
A 20-character alphanumeric code that identifies one legal entity globally, issued under an international system originally set up so regulators could see who was on each side of a financial transaction.
