## 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.

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

## California Contractor Directory by Trade & County (CSLB)

Pull every licensed contractor in a California county by trade — business name, contact details, license status, classifications, bond, and workers' comp — straight from the official CSLB registry. One run returns a clean, structured list ready for lead generation, CRM import, license verification, or market analysis.

### 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
{
  "licenseClass": "C-10",
  "county": "Los Angeles",
  "maxResults": 1000
}
````

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

### What you get

One row per record:

| Field | Description |
|---|---|
| `license_number` | CSLB license number |
| `business_name` | Licensed business name |
| `business_type` | Sole Owner, Corporation, LLC, Partnership… |
| `address` | Business street address |
| `city` | City |
| `county` | County |
| `zip_code` | ZIP code |
| `phone` | Business phone |
| `classifications` | All classification codes held (e.g. \["A","C10"]) |
| `status` | License status (e.g. CLEAR) |
| `issue_date` | Original license issue date |
| `expiration_date` | License expiration date |
| `surety_company` | Contractor bond surety company |
| `bond_number` | Contractor bond number |
| `workers_comp_type` | Workers' comp coverage type (Insurance / Exempt / …) |
| `workers_comp_company` | Workers' comp insurance carrier |
| `source_url` | Link to the official CSLB license detail page |

Sample:

```json
{
  "license_number": "22726",
  "business_name": "RANSOME COMPANY",
  "business_type": "Corporation",
  "address": "1933 WILLIAMS STREET",
  "city": "SAN LEANDRO",
  "county": "Alameda",
  "zip_code": "94577",
  "phone": "(510) 686 9900",
  "classifications": [
    "A",
    "C10"
  ],
  "status": "CLEAR",
  "issue_date": "07/01/1932",
  "expiration_date": "10/31/2027",
  "surety_company": "HARCO NATIONAL INSURANCE COMPANY",
  "bond_number": "354811",
  "workers_comp_type": "Workers' Compensation Insurance",
  "workers_comp_company": "TRAVELERS PROPERTY CASUALTY COMPANY OF AMERICA",
  "source_url": "https://www.cslb.ca.gov/onlineservices/checklicenseII/LicenseDetail.aspx?LicNum=22726"
}
```

### Inputs

| Field | Required | Type | Default | Description |
|---|---|---|---|---|
| `licenseClass` | yes | string | `"C-10"` | CSLB classification code, e.g. 'B' (General Building), 'C-10' (Electrical), 'C-36' (Plumbing). Returns every active contractor holding this classification in the chosen county. |
| `county` | yes | string | `"Sacramento"` | Full California county name, e.g. 'Los Angeles', 'Sacramento', 'Orange'. |
| `maxResults` | no | integer | — | Cap on the number of license records returned in a single run. Leave empty to return all matches. |
| `proxyConfiguration` | no | object | `{"useApifyProxy": false}` | Optional. CSLB is usually reachable directly; enable a proxy (e.g. residential) only if runs return no data because the IP is blocked. |

### Pricing (Pay Per Event)

You pay per result (`dataset-item`) — **no charge for empty runs**. Example: **500 C-10 electricians in Los Angeles County** at *$0.002/result* ≈ **$1.00**.

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

### Use cases

- B2B lead lists — target licensed trades (electricians, plumbers, general builders) by county for suppliers, SaaS, insurers, and lenders.
- License verification & compliance — confirm a contractor's status, bond, and workers' comp coverage.
- Market analysis — size and segment the contractor market by classification and county.

### Limitations & updates

Covers California's CSLB public registry only (public record under Business & Professions Code §7000 et seq.). Results reflect the live registry and change as it updates. One classification + county per run.

### Which actor to choose

Part of the California CSLB contractor suite — pick the one that fits your goal:

- **California Contractor Directory by Trade & County (CSLB)** *(this actor)* — You want a bulk lead list — every licensed contractor of a given trade (classification) in a county, in one run.
- **California Contractor License Lookup & Verify (CSLB)** — You want to verify or look up specific contractors — by license number, business name, or a person's name (owner/personnel).

# Actor input Schema

## `licenseClass` (type: `string`):

  "county": "Sacramento",
  "proxyConfiguration": {
    "useApifyProxy": false
  }

    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "licenseClass": "C-10",
    "county": "Sacramento"
};

// Run the Actor and wait for it to finish
const run = await client.actor("fried_calamaries/california-contractor-directory").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
