## About

## What it does
Company KYB Lookup helps you verify and enrich business records from a few identifiers. Send a company `lei`, `vat`, `name`, `country`, and an optional `limit`, and get back a JSON envelope with a numeric `code`, a `success` flag, and module blocks in the response body.

Use it when you need to check whether a business is real, match a customer record against known company identifiers, or reduce manual review in onboarding and compliance flows. Because the endpoint accepts either an LEI, VAT number, or company name, you can start with whatever identifier you already have in your system.

The response is wrapped in a simple envelope, so you can branch on `success` and `code` before reading the returned module data. That makes it a fit for KYB checks, vendor onboarding, account verification, and internal lookup tools where you need a structured company result without building your own registry search layer.

Set `limit` when you want to control how many matches are returned, up to 25.
