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).

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.

Look up a California contractor by:

• License number (6–8 digits, e.g. 700000)
• Business name (full or partial)

For each match it returns a structured record with the full license profile.
