Inputs

Field	Type	Req	Default	Description
`query`	string	no	`"CONSTRUCTION"`	A Minnesota DLI residential-contractor license number, business name, or person name to verify or search. Searches by exact license number and by business/DBA name substring. Leave this and 'Search query (batch)' empty to export the statewide roster instead, narrowed by the filters below.
`queries`	array	no	`["CONSTRUCTION"]`	Look up many in ONE run instead of starting a run per lookup. Takes the same values as 'Search query'. Combined with 'Search query' if you fill both, and duplicates are removed. Billing is unchanged: you are charged per record returned, not per entry submitted.
`licenseSubtype`	string	no	—	One DLI licence subtype: Qualifying Builder, Residential Building Contractor, Qualifying Remodeler, Residential Remodeler Contractor, Qualifying Roofer, Residential Roofer Contractor, Qualifying Installer, Manufactured Home Installer or Certificate of Exemption. Short words work too: 'builder', 'remodeler', 'roofer', 'installer' (each covers both its business licence and its qualifying-person licence), 'exemption'. Empty = every subtype. An unrecognised value is ignored with a log line; if nothing you gave is recognised, the run returns a free row saying so instead of the whole state.
`licenseSubtypes`	array	no	`[]`	Several subtypes in ONE run. Combined with 'Licence subtype' if you fill both.
`status`	string	no	—	active (DLI 'Issued'), expired, voluntary_termination, revoked, suspended, withdrawn, or all. Empty = active when exporting statewide, and every status when you give a search query (so existing lookups behave exactly as before).
`statuses`	array	no	`[]`	Several statuses in ONE run, e.g. revoked and suspended. Combined with 'Licence status' if you fill both.
`city`	string	no	—	Business city, exact match ignoring case and punctuation; 'St Paul', 'St. Paul' and 'Saint Paul' are the same city (DLI spells it both ways).
`cities`	array	no	`[]`	Several cities in ONE run. Combined with 'City' if you fill both. The roster has no county column, so filter by city or ZIP.
`zip`	string	no	—	Business ZIP, 5 digits (a ZIP+4 is matched on its first 5).
`zips`	array	no	`[]`	Several ZIPs in ONE run. Combined with 'ZIP code' if you fill both.
`maxResults`	integer	no	—	With a search query: cap on matches PER QUERY (default 50), so a batch cannot silently return only the first rows overall and read as 'no match'. Statewide export: cap for the whole run (default 500, a spend control). The full roster is 59,302 licences (25,359 active, measured 2026-10-07), so 100000 returns everything that matches; the run log states how many matched when the cap cuts it short.
`enforcementOnly`	boolean	no	`false`	When on, return only licensees with a DLI enforcement action on record (revocation, suspension, etc.). Works with a search query or statewide. Note: a statewide export defaults to active licences; set status to 'all' to include the revoked and expired licences most enforcement actions sit on.
`proxyConfiguration`	object	no	`{"useApifyProxy":false}`	Optional. The Minnesota DLI roster CSV is reachable directly; a proxy is not needed.

FAQ

Where does the data come from?

The official Minnesota Department of Labor & Industry (DLI) residential-contractor licensee roster — a public dataset the state refreshes nightly.

What can I search by?

A DLI license number (exact) or a business/person name (substring, matches the DBA name too). Both return the matching licenses, deduped by license number. Leave the search empty to export the statewide roster instead, filtered by licence subtype, status, city or ZIP.

How big is a full export?

Measured 2026-10-07: 59,302 licences in the roster, 25,359 of them active (DLI status 'Issued'). An export defaults to active licences and 500 rows; set status to 'all' and maxResults to 100000 for everything. There is no county column in DLI's file, so narrow by city or ZIP.

What's the enforcement-action flag?

DLI publishes whether a licensee has an enforcement action on record. We surface that flag on every result, and 'Enforcement monitor mode' returns only licensees currently under one.

What fields do I get?

License number, business/person name, license subtype, status, original and expiration dates, city, address, ZIP, phone (when published), the enforcement-action flag, and a renewal-in-progress flag.

How am I charged?

Pay-per-result — per license match returned. No charge for searches with no results.

Is this personal data?

It's public professional-license data as DLI publishes it. We deliberately skip the roster's email column and add no personal/PII enrichment.
