Live coverage

Statewide residential business licenses and construction contractor registrations

Refresh cadence

Expected daily after nightly source publication

Two DLI datasets

The residential contractor CSV supplies eligible business licenses. A separate construction contractor registration CSV supplies registrations. The API retains their credential kinds and source statuses.

Search MN records by business name and optional license_type.
Verify a known number and compare identity, type, and status.
Use credential_kind to distinguish registration from license.

Production refresh

Minnesota jobs are expected daily after DLI's nightly publication. Review timestamps for the specific record and confirm material decisions with DLI.
