## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

# README

## Minnesota Contractor License Lookup & Verify (DLI)

### Pain points

- Verifying a Minnesota residential contractor on the DLI site is one slow manual lookup at a time.
- The DLI portal won't tell you at a glance whether a licensee is under an enforcement action.
- Screening many contractors — or monitoring a name for disciplinary flags — doesn't scale by hand.

### What we solve

- Verify any Minnesota DLI residential contractor, remodeler, roofer, or installer by license number or business/person name — one search.
- Surfaces the DLI enforcement-action flag on every record, plus an 'enforcement monitor' mode that returns only licensees under enforcement.
- Returns license subtype, status, effective & expiration dates, city, address, and phone from the official registry; pay per match, empty searches free.

### Summary

Look up and verify any Minnesota residential contractor from a single search — type a DLI license number or a business/person name and get back the license subtype (Residential Building Contractor, Qualifying Builder, Remodeler, Roofer, Installer), status, effective and expiration dates, city, address, phone, and — the part the DLI site buries — an enforcement-action flag showing whether the licensee has been disciplined. Flip on enforcement-monitor mode to return only licensees currently under a DLI enforcement action. Built for fast verification, subcontractor vetting, compliance screening, and disciplinary monitoring, straight from the official Minnesota DLI licensee registry.

### Who it's for

- GCs and hiring managers vetting Minnesota subcontractors
- Compliance teams monitoring contractors for enforcement/disciplinary flags
- Insurance underwriters and lenders running KYC on contractors
- RevOps and BD teams enriching contractor records

### How to use

Set the input, run the actor, and collect results from the run's dataset (export to JSON/CSV/Excel, or pull via the Apify API). Example input:

```json
{
  "query": "CONSTRUCTION",
  "maxResults": 25
}
````

See **Inputs** below for every available field.

### What you get

One row per record:

| Field | Description |
|---|---|
| `state` | Licensee's registered state (usually 'MN') |
| `license_number` | DLI license number (e.g. BC807688) |
| `business_name` | Licensed business name (DBA appended when present) |
| `person_name` | Individual's name when the licensee is a person, else null |
| `license_type` | License type + subtype (e.g. 'Residential Contractors - Qualifying Builder') |
| `status` | License status (e.g. Issued, EXPIRED, REVOKED, SUSPENDED) |
| `issue_date` | Original license date |
| `expiration_date` | License expiration date |
| `city` | Business city |
| `address` | Business street address |
| `zip_code` | ZIP code |
| `phone` | Business phone (when published) |
| `enforcement_action` | Flag set when the licensee has a DLI enforcement action; null otherwise |
| `renewal_in_progress` | 'Yes' when a renewal is pending, else null |
| `matched_by` | Which search surfaced this match: 'license\_number' or 'business\_name' |
| `source_url` | The official DLI roster source |

Sample:

```json
{
  "state": "MN",
  "license_number": "RR531208",
  "business_name": "RASSMUSSEN METAL ROOFING AND CONSTRUCTION INC (dba RMR CONSTRUCTION INC)",
  "person_name": null,
  "license_type": "Residential Contractors - Residential Roofer Contractor",
  "status": "REVOKED",
  "issue_date": "06/20/2005",
  "expiration_date": "03/31/2008",
  "city": "MINNEAPOLIS",
  "address": "5536 27TH AVE S",
  "zip_code": "55417",
  "phone": null,
  "enforcement_action": "1",
  "renewal_in_progress": null,
  "matched_by": "business_name",
  "source_url": "https://secure.doli.state.mn.us/ccld/data/MNDLILicRegCertExport_Residential_Contractors.csv"
}
```

### Inputs

| Field | Required | Type | Default | Description |
|---|---|---|---|---|
| `query` | yes | string | `"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. |
| `maxResults` | no | integer | `50` | Cap on matches returned (bounds cost). |
| `enforcementOnly` | no | boolean | `false` | When on, return only licensees with an active DLI enforcement action (revocation, suspension, etc.). Use this to monitor a name/keyword for disciplinary flags. |
| `proxyConfiguration` | no | object | `{"useApifyProxy": false}` | Optional. The Minnesota DLI roster CSV is reachable directly; a proxy is not needed. |

### Pricing (Pay Per Event)

You pay per result (`dataset-item`) — **no charge for empty runs**. Example: **100 verified license records** at *$0.004/result* ≈ **$0.40**.

Illustrative — the final per-result price is set at publish time. Apify platform usage (compute) is billed separately per your plan.

### Use cases

- License verification — confirm a Minnesota contractor's subtype, status, and expiration before hiring or onboarding.
- Enforcement monitoring — flip on enforcement-only mode to surface any licensee under a DLI enforcement action for a name or keyword.
- Compliance screening — pull the enforcement-action flag on demand for audits, due diligence, and marketplace vetting.
- Record enrichment — turn a license number or name into a full structured record for a CRM or vetting workflow.

### Why this actor

- Straight from the official Minnesota DLI licensee registry — authoritative, refreshed nightly, not a stale third-party copy.
- The only lookup here that flags enforcement actions on every record — and an enforcement-monitor mode to isolate them.
- Search by license number or business/person name; results deduped by license #. Pay per match; empty searches are free.

### Limitations & updates

Covers Minnesota's DLI residential-contractor licensee roster only (residential building contractors, remodelers, roofers, installers, and related certificates) — not electrical, plumbing, or other trade boards. Results reflect the nightly roster snapshot and change as it updates. A name search matches the business/DBA-name index; runs are bounded (default 50 results) — refine a broad name to narrow it. The enforcement-action field is DLI's published flag (presence of an action), not the case detail. Bond and insurance details are not part of this roster and are returned null.

### 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.

**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.
