## 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).

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

# README

## US License Verification API — Contractors & Professionals (11 States)

**Verify and normalize US professional & contractor licenses across 11 states into one clean, consistent schema.** Send a license number (or a name) for any supported state and get back a normalized record — status, classification, expiration, bond, and a disciplinary flag — straight from the official state licensing-board public records, with a source link and verification timestamp on every result.

A single **contractor license verification API** and **license lookup API** for bulk checks, KYB / vendor onboarding, and compliance monitoring. Stop writing and maintaining a different scraper for every state board. One input shape, one output shape, eleven states — built for lenders, sureties, insurers, vendor-onboarding and compliance teams, contractor lead-gen, and AI agents that need a fast, auditable license check.

### Why this Actor

- **One normalized schema across every state.** `licenseNumber`, `licenseeName`, `status` (active / inactive / expired / suspended / revoked / unknown), `classification`, `bondStatus`, `disciplinaryFlag`, `issueDate`, `expirationDate`, `sourceUrl`, `verifiedAt`.
- **You only pay when we find a match.** No charge for a clean "not found", an unsupported state, or a source error — ever.
- **Auditable by design.** Every record carries the exact `sourceUrl` it was derived from and a `verifiedAt` timestamp.
- **Two ways to query:** by license number, or by licensee / business name.
- **Two pricing tiers:** a full record, or a cheaper status-only check for recurring renewal/compliance monitoring.

### Coverage (11 states)

| State | Source (official) |
|------|--------------------|
| CO | Colorado DORA — professional & occupational licenses |
| TX | Texas TDLR — regulated licensees |
| WA | Washington L&I — registered contractors |
| OR | Oregon CCB — construction contractors (incl. bond) |
| IL | Illinois IDFPR — professional licenses (incl. disciplinary flag) |
| NY | New York — contractor registry |
| CT | Connecticut eLicense — all credentials |
| DE | Delaware — professional regulation |
| AR | Arkansas Contractors Licensing Board |
| VA | Virginia DPOR — contractors (Class A/B/C) |
| VT | Vermont Division of Fire Safety — electrical, plumbing & trade licenses |

**Coming soon:** Florida (DBPR construction), North Carolina, West Virginia. More states are added continuously — need one that isn't here yet? Request it.

### Why not just build it yourself?

Verifying licenses across states is death by a thousand scrapers. Every board ships its data in a different shape — some as open-data APIs, some as 40 MB CSVs, some only behind a JavaScript form — and they break **silently** when a column gets renamed or a portal moves. You'd write one scraper per board, then maintain all of them forever.

This Actor collapses that into one call. We absorb the per-state format drift, normalize everything into a single schema, and run a daily health canary against every source so breakage is caught **before** it reaches your results — never returned to you as a misleading "no match." You pay only when we deliver a verified record.

### Input

```json
{
  "queries": [
    { "route": "CO", "params": { "licenseNumber": "711991" } },
    { "route": "WA", "params": { "licenseNumber": "ECOSTSC758NN" } },
    { "route": "TX", "params": { "name": "ABC Plumbing" } }
  ],
  "mode": "full"
}
````

- **`queries`** — one or more lookups. Each is `{ "route": <2-letter state>, "params": { "licenseNumber": "…" } }`, or use `"name"` to search by licensee/business name.
- **`mode`** — `full` (default, complete record) or `status` (status-only, cheaper).
- **`maxResultsPerQuery`** *(optional)* — a license number can match more than one license type; default 50.
- **`socrataAppToken`** *(optional)* — a free Socrata token raises rate limits for high-volume runs.

### Output

One flat row per result.

```json
{
  "result": "found",
  "state": "OR",
  "licenseNumber": "100215",
  "licenseeName": "BRUCE HUIE",
  "status": "active",
  "classification": "RGC (Residential General Contractor)",
  "bondStatus": "$25,000 bond with WESTERN SURETY COMPANY (expires 2028-02-06)",
  "bondAmount": 25000,
  "bondCompany": "WESTERN SURETY COMPANY",
  "bondExpirationDate": "2028-02-06",
  "disciplinaryFlag": null,
  "issueDate": "1994-06-20",
  "expirationDate": "2028-02-06",
  "asOf": null,
  "sourceUrl": "https://data.oregon.gov/resource/g77e-6bhs.json?$where=…",
  "verifiedAt": "2026-05-31T12:00:00.000Z"
}
```

`result` is `found`, `not_found`, or `source_error`. Only `found` rows are billed.

### Pricing

Pay-per-event — you pay per **successful** verification:

| Event | What you get | Price |
|------|---------------|-------|
| `license-verified` | Full normalized record | **$0.03** |
| `status-check` | Status-only result (use `mode: "status"`) | **$0.01** |

No subscription, no charge on misses. For comparison, dedicated verification APIs typically charge $0.20–$0.50+ per lookup.

### How it works

For each query the Actor routes to that state's official open-data source, fetches the matching record(s), and normalizes them into the shared schema. Where a board doesn't publish an explicit status, status is derived from the expiration date against the current public roster (i.e. "present and unexpired", not a positively-asserted flag) — this is noted per record's source.

### FAQ

**Is the data official?** It comes from official state licensing-board public records, but this Actor is unofficial and not affiliated with any board. Always confirm directly with the board before relying on a result.

**How fresh is it?** Each record shows `verifiedAt` (when we fetched it) and, where the source exposes it, `asOf` (the source's own refresh date). Some states publish daily; bulk-file states refresh on the board's own schedule.

**Can I bulk-verify?** Yes — pass many items in `queries`. A license number that maps to multiple license types returns multiple rows.

**Can I use this for employment, tenant, credit, or insurance screening?** **No.** See the disclaimer below.

### Legal & acceptable use

> **NOT A CONSUMER REPORT / NOT FCRA-COMPLIANT.** This Actor and its output are **not** a consumer report and the operator is **not** a consumer reporting agency under the Fair Credit Reporting Act (15 U.S.C. § 1681 et seq.). Do **not** use this data, in whole or in part, to establish eligibility for **employment, credit, insurance, housing/tenancy**, or any other FCRA-covered purpose. For those purposes, obtain a consumer report from a properly licensed consumer reporting agency.

> **Source & accuracy.** Data is sourced from official state licensing-board **public records** and reflects the source as of each record's `verifiedAt` timestamp. It may be incomplete, delayed, or out of date, and is an **unofficial** reflection — always confirm license status directly with the relevant state board before relying on it. Provided **as-is**, with no warranty of accuracy, completeness, or fitness for a particular purpose; not legal or compliance advice.

> **Unofficial / no affiliation.** This Actor is not affiliated with, sponsored by, endorsed by, or certified by any state licensing board, government agency, or data provider.

> **Your responsibility.** You are solely responsible for ensuring your use complies with the terms of use, open-data license, and applicable open-records / anti-solicitation laws of each source jurisdiction. **Prohibited uses** include FCRA-covered screening, unsolicited marketing/solicitation to licensees, building competing databases where source terms forbid it, and any unlawful, harassing, or stalking purpose.

# Actor input Schema

## `queries` (type: `array`):

One or more license lookups. Each item is { "route": <2-letter state code>, "params": { "licenseNumber": "..." } } — or use "name" instead of "licenseNumber" to search by licensee/business name. Supported states: CO, TX, WA, OR, IL, NY, CT, DE, AR, VA, VT.

## `mode` (type: `string`):

full = complete normalized record (billed as license-verified). status = status-only result, cheaper (billed as status-check).

## `maxResultsPerQuery` (type: `integer`):

Cap on records returned per query (a license number can match multiple license types).

## `socrataAppToken` (type: `string`):

A free Socrata app token raises anonymous rate limits for high-volume runs against the Socrata-backed states. Leave blank otherwise.

## `useApifyProxy` (type: `boolean`):

Route requests through Apify Proxy (only needed for proxy-required states added later; the 11 current states do not need it).
