## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Washington Contractor License Lookup & Verify (L\&I)

### Pain points

- Verifying a Washington contractor on the L\&I 'Verify a Contractor' portal is one slow manual lookup at a time.
- The portal isn't structured for compliance workflows, subcontractor vetting, or CRM enrichment.
- Checking status, license type, and expiration across many licensees by hand doesn't scale.

### What we solve

- Verify any Washington L\&I contractor or tradesperson by license number or business name - one search.
- Returns license type, status, effective & expiration dates, city, and principal name from the official registry.
- Enrich a license number or name into a full structured record; pay per match, empty searches free.

### Summary

Look up and verify any Washington State contractor or tradesperson from a single search - type an L\&I contractor registration number or a business name and get back the license type, status, effective and expiration dates, city, and principal name, straight from the official Washington L\&I open-data registry. Built for fast verification, compliance checks, subcontractor vetting, and enriching a license number or name into a structured record.

### Who it's for

- GCs and hiring managers vetting Washington subcontractors
- Insurance underwriters and lenders running KYC on contractors
- Compliance teams and marketplaces verifying L\&I registrations
- 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` | Always 'WA' for this actor |
| `license_number` | L\&I contractor registration / license number |
| `business_name` | Licensed business name |
| `person_name` | Primary principal / owner name |
| `license_type` | L\&I license type (e.g. Construction Contractor) |
| `status` | License status (e.g. ACTIVE, EXPIRED, RE-LICENSED) |
| `issue_date` | License effective date |
| `expiration_date` | License expiration date |
| `city` | Business city |
| `address` | Business street address |
| `zip_code` | ZIP code |
| `phone` | Business phone (when published) |
| `matched_by` | Which search surfaced this match: 'license\_number' or 'business\_name' |
| `source_url` | Link to the official L\&I verification portal |

Sample:

```json
{
  "state": "WA",
  "license_number": "ECOSTSC758NN",
  "business_name": "!ECO STAR C G CONSTRUCTION LLC",
  "person_name": "GUERRERO MARTINEZ, CARLOS I.",
  "license_type": "CONSTRUCTION CONTRACTOR",
  "status": "ACTIVE",
  "issue_date": "2025-08-15T00:00:00.000",
  "expiration_date": "2027-08-15T00:00:00.000",
  "city": "VANCOUVER",
  "address": "2420 COLUMBIA HOUSE BLVD #311",
  "zip_code": "98661",
  "phone": "5039573452",
  "matched_by": "business_name",
  "source_url": "https://secure.lni.wa.gov/verify/"
}
```

### Inputs

| Field | Required | Type | Default | Description |
|---|---|---|---|---|
| `query` | yes | string | `"construction"` | A Washington L\&I license number or business name. Searches by exact license number and by business-name substring; principal names are returned on the row but are not searchable. |
| `maxResults` | no | integer | `50` | Cap on matches returned (bounds cost). This is now honoured end to end - the Socrata query is issued for this many rows. |
| `proxyConfiguration` | no | object | `{"useApifyProxy": false}` | Optional. The Washington L\&I open-data API 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 Washington contractor's type, status, and expiration before hiring or onboarding.
- Record enrichment — turn a license number or name into a full structured record for a CRM, marketplace, or vetting workflow.
- Compliance checks — pull authoritative L\&I data on demand for audits and due diligence.
- Lender / insurer due diligence — verify a contractor's standing straight from the state registry.

### Why this actor

- Straight from the official Washington L\&I open-data registry — authoritative, not a stale third-party copy.
- Search by license number (exact) or business name (substring); results deduped by license #.
- Pay per match; searches with no results are free.

### Limitations & updates

Covers Washington's L\&I contractor-registration public registry only. Results reflect the published open-data snapshot (refreshed on business days) and change as it updates. A name search matches the business-name index; runs are bounded (default 50 results) — refine a broad name to narrow it. Bond, workers-comp, and insurance details live in separate L\&I datasets and are not joined in this version (returned null); county and some fields are not published for every record.

### FAQ

**Where does the data come from?**

The official Washington State Department of Labor & Industries (L\&I) contractor-registration open-data registry — public, authoritative license data.

**What can I search by?**

An L\&I contractor registration/license number (exact) or a business name (substring). Principal name is returned on each record but it is not itself searchable.

**What fields do I get?**

License number, business name, principal name, license type, status, effective and expiration dates, city, address, ZIP, and phone when published.

**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 (business and registration records as L\&I publishes them); we add no personal/PII enrichment.

**How current is it?**

It reflects the L\&I open-data registry, which the state refreshes on business days.
