Contractor License Search USA: contractor leads from 13 official license databases in 9 states

Contractor license search across California (CSLB, 120,000+ licensed businesses), Washington, Oregon (two boards), Texas, New York State, New York City, Maryland (Montgomery County), Tennessee (Nashville), Ohio (Cleveland) and Colorado (Boulder) in one run and one clean schema. Get licensed contractor businesses with license number, license type, trade, status, issue and expiration dates, business address and business phone, straight from the official state and city licensing agencies.

Use it as a contractor lookup / contractor license API, to build contractor lead lists (roofing, HVAC, electrical, plumbing, solar, general contractors), to verify subcontractors, or to catch newly licensed contractors the week they get their license.

Free to try: Apify's free plan ($5/month in credit, no card needed) covers about 3,300 records a month. Price: $1.50 per 1,000 results, below typical contractor-license tools in the Store.

No browser, no proxies, no login, no API key. The Actor reads each state's public open-data API, so most runs take seconds (California adds 1-3 minutes to download the CSLB master file).
