# Baselayer

> Verify US businesses and retrieve KYB data: officers, registrations, risk scores.

[Baselayer](https://baselayer.com) is a Know Your Business (KYB) platform that
verifies US entities against authoritative registration and risk data. It
resolves a business by name and address and returns the full profile: officers,
state registrations, entity structure, and verification status.

## Use it for

* KYB onboarding and vendor/customer verification.
* Due diligence on officers, registrations, and entity structure.
* Screening businesses for risk and watchlist hits.

## Provider ID

Use this value in `dataSources`:

```text theme={null}
baselayer
```

## Example

Verify a business and retrieve its officer and registration details.
