Can I list the subsidiaries?

Yes, with LEI Lookup company relationships, which returns direct and ultimate children of a LEI.

Do I pay for lookups that come back empty?

No. You are charged per result, so a request that finds nothing costs nothing. Testing this against a messy list is free to get wrong.

What does a lookup cost?

5 points per resolved lookup, which is $5 per 1,000, and only successful lookups are charged. Points come out of your monthly plan allowance, so there is no separate per-country contract.

LEI Lookup API and MCP — Entity, Renewal and Parent Data by LEI Code

Send a LEI code, or a link to the record on lei-lookup.com, and get that Legal Entity Identifier record from the public LEI register: name, entity and LEI status, registration and renewal dates, managing issuer, legal form, registration authority, legal and headquarters addresses, parent companies and the number of subsidiaries.

Run it in the app Read the API docs

You send: a 20-character LEI code or a lei-lookup.com record link
You get back: Name, entity and LEI status, registration and renewal dates, managing issuer, legal form, registration authority, addresses, parents and subsidiary counts
Coverage: Records on LEI Lookup (lei-lookup.com).
Price: 5 pts — $5 per 1,000; Charged only when the record resolves. A lookup that finds nothing is not billed.

Comparison

Ways to get this data

Three approaches teams use today, and where each one runs into trouble.

Approach	What it takes	Cost	Trade-off
LEI Lookup (lei-lookup.com) directly	Open LEI Lookup (lei-lookup.com) and read the record	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 the register named on this page — other countries are separate sources with the same request format

Integration

How to run it

The same lookup works from the app, the API, or as a tool an agent can call mid-task.

One company per request. Pass the registration number or the link to the record on the register.

curl -X POST https://api.neuralverge.ai/functions/v1/run-lei-lookup-companies \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"company":"HWUPKR0MPOU8FGXBT394"}'

Use cases

What teams use it for

Where this field shows up in an actual workflow.

LEI validation

Check that a LEI exists, who manages it and when it was last updated.

Renewal tracking

Read next_renewal_date to find LEIs that are about to lapse.

Entity matching

Use the registration authority and number to match a LEI to a national register entry.

Group size

Read subsidiary counts for a first sense of a group before you list the children.

Coverage & limits

Coverage, freshness and limits

What this source covers, how fresh it is, and where it stops.

Coverage

Records on LEI Lookup (lei-lookup.com).

Freshness

Read at request time, so the answer reflects the register as it stands when you ask.

Handling

LEI Lookup (lei-lookup.com) is a public register. Every response carries the source URL it was read from and a session id you can trace.

What it will not do

—Only entities that hold a LEI are in the register.
—The record gives subsidiary counts; the children themselves come from LEI Lookup company relationships.
—Lookup is by LEI or record link. Use LEI Lookup search to find a LEI from a name.
