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. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## CSLB California Contractor License Verification Apify Actor that verifies **California contractor licenses** directly from the official **Contractors State License Board (CSLB)** "Check a License" database ([cslb.ca.gov](https://www.cslb.ca.gov/onlineservices/checklicenseII/checklicense.aspx)). Built for general contractors, sub-hiring, property managers, insurers, lenders, and compliance teams that must confirm a contractor is **licensed, bonded, and able to contract** before signing a deal or hiring on a project. ### What it does Look up a California contractor by: - **License number** (6–8 digits, e.g. `700000`) - **Business name** (full or partial) - **Personnel name** (associated officer / owner — last name, optional first name) For each match it returns a structured record with the full license profile. ### Output Each dataset item: | Field | Description | |-------|-------------| | `state` | Always `CA` | | `source` | Always `CSLB` | | `found` | `true` if the license exists, `false` if not in the database | | `licenseNumber` | The CSLB license number | | `businessName` | Licensed business name | | `address` | Mailing/business address | | `businessPhone` | Phone number on file | | `entityType` | e.g. Sole Ownership, Corporation, Partnership, LLC | | `issueDate` | License issue date | | `expireDate` | License expiration date | | `status` | Normalized status: `Active`, `Expired`, `Suspended`, `Revoked`, `Inactive`, ... | | `statusDescription` | Full CSLB status sentence | | `classifications` | Array of classifications, e.g. `["B - GENERAL BUILDING CONTRACTOR", "C-10 - ELECTRICAL"]` | | `bonding` | Contractor's bond: `company`, `bondNumber`, `bondAmount`, `effectiveDate`, `cancellationDate` | | `workersCompensation` | Workers' comp status / carrier / dates | | `disciplinaryFlag` | `true` if revoked/suspended or disclosable actions are present | | `detailUrl` | Link to the CSLB detail page | | `scrapedAt` | ISO timestamp of the lookup | #### Example record ```json { "state": "CA", "source": "CSLB", "found": true, "licenseNumber": "700000", "businessName": "RELIABLE TREE EXPERTS", "address": "3613 DAVIS AVE, MODESTO, CA 95357", "businessPhone": "(209) 579-8733", "entityType": "Sole Ownership", "issueDate": "12/08/1994", "expireDate": "12/31/2012", "status": "Expired", "statusDescription": "This license is expired and not able to contract at this time.", "classifications": ["C-61 / D49 - TREE SERVICE"], "bonding": { "company": "AMERICAN CONTRACTORS INDEMNITY COMPANY", "bondNumber": "SC6016130", "bondAmount": "$12,500", "effectiveDate": "03/02/2009", "cancellationDate": "02/02/2013" }, "workersCompensation": "This license is exempt from having workers compensation insurance; ...", "disciplinaryFlag": false, "detailUrl": "https://www.cslb.ca.gov/onlineservices/checklicenseII/LicenseDetail.aspx?LicNum=700000", "scrapedAt": "2026-06-24T18:51:05.000Z" } ```` ### Input ```json { "searchType": "licenseNumber", "licenseNumber": "700000", "proxyConfiguration": { "useApifyProxy": true, "apifyProxyGroups": ["RESIDENTIAL"] } } ``` | Input | Type | Notes | |-------|------|-------| | `searchType` | string | `licenseNumber` (default), `businessName`, or `personnelName` | | `licenseNumber` | string | Required for `licenseNumber` searches | | `businessName` | string | Required for `businessName` searches | | `lastName` | string | Required for `personnelName` searches | | `firstName` | string | Optional, narrows a personnel-name search | | `maxResults` | integer | Cap on licenses resolved per name search (default 25) | | `proxyConfiguration` | object | Defaults to Apify RESIDENTIAL proxy | ### Use cases - **Hiring & subcontracting** — confirm a contractor is active and bonded before signing. - **Insurance & lending** — validate license status and workers' comp for underwriting. - **Lead generation** — enrich contractor lists with classifications and contact info. - **Compliance / due diligence** — flag expired, suspended, or revoked licenses. ### Pricing Pay-per-result: a small fee per license record returned, plus a tiny actor-start fee. ### Notes Data comes from the public CSLB database and reflects whatever CSLB has on file ("Data current as of …" appears on each detail page). This Actor is an independent tool and is not affiliated with or endorsed by the CSLB or the State of California. # Actor input Schema ## `searchType` (type: `string`): How to look up the license: by license number, by business name, or by personnel (officer/owner) name. ## `licenseNumber` (type: `string`): CSLB license number (6-8 digits), e.g. 700000. Required when search type is License Number. ## `businessName` (type: `string`): Contractor business name (or part of it). Required when search type is Business Name. ## `lastName` (type: `string`): Last name of an associated person (officer/owner). Required when search type is Personnel Name. ## `firstName` (type: `string`): Optional first name to narrow a personnel-name search. ## `maxResults` (type: `integer`): Maximum number of licenses to resolve for name searches (each match is fetched in full). ## `proxyConfiguration` (type: `object`): Proxy settings. The CSLB site is not captcha-walled, but RESIDENTIAL proxies are recommended for reliability and to avoid rate limiting. ## Actor input object example ```json { "searchType": "licenseNumber", "licenseNumber": "700000", "maxResults": 25, "proxyConfiguration": { "useApifyProxy": false } } ``` # Actor output Schema ## `results` (type: `string`): No description # API You can run this Actor programmatically using our API.
