California CSLB Contractor License Scraper

Free-plan limit: Apify free-plan users receive at most 5 delivered license records per run. Paid and agentic-payment runs may use the configured maxResults limit.

Scrape the California Contractors State License Board (CSLB) public database for full contractor license records. Search by license number, business name, personnel name, or ZIP code — get status, all classifications, bonds, workers' comp, disciplinary actions, personnel, and full contact details in structured JSON.

Use cases

• Contractor verification — confirm a contractor is licensed and in good standing before hiring
• Compliance monitoring — detect newly expired, suspended, or revoked licenses for vendor lists on recurring schedules
• Lead generation — build targeted lists of licensed contractors by ZIP code, city, classification, or active status
• Subcontractor sourcing — find qualified subcontractors by specialty classification and region
• Insurance underwriting — score contractors using disciplinary actions, bond cancellation history, and workers' comp status
• Due diligence — check complaint and legal action history before signing contracts
• Market research — analyze contractor density by county/classification, track new-license issuance trends
