## 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

## 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.

| `state` | Always `CA` |

| `status` | Normalized status: `Active`, `Expired`, `Suspended`, `Revoked`, `Inactive`, ... |
| `statusDescription` | Full CSLB status sentence |

| `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 |

  "proxyConfiguration": { "useApifyProxy": true, "apifyProxyGroups": ["RESIDENTIAL"] }
}
```

- **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.

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.
