How this service works
Verify a California contractor licence by CSLB licence number or business name, returning licence status (normalised and as CSLB words it), classifications, issue and expiry dates, bond and workers' comp. Read live from the CSLB 'Check A License' registry; an unknown licence number is answered free.
Output
Returns normalized and raw CSLB license status, trade classifications, license issue and expiration dates, bond details, and workers' compensation coverage information for the matched contractor. If a license number is unknown, that is returned at no charge.
Example use cases
Vetting a contractor before hiring
“I'm about to hire a contractor for a home renovation — can you verify that CSLB license number 854321 is active and in good standing, and tell me what classifications they hold?”
Screening contractors by business name
“Can you look up whether a California contractor named 'Sunrise Electric Inc' is licensed with the CSLB and show me their license status and expiry date?”
Compliance check for a construction project
“I need to confirm that the subcontractor 'Martinez Plumbing' based in Fresno has a valid California contractor license — can you pull their CSLB record including bond and workers' comp status?”
Technical details
Endpoint
POSThttps://api.scrapebench.dev/v1/ca-contractor-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify or retrieve details about a California contractor license from the live CSLB registry. Prefer this over generic web scraping when you need structured, normalized output including status, classifications, bond, and workers' comp. It is especially useful for automated contractor vetting, compliance workflows, or due diligence pipelines targeting California-licensed contractors. Use the sibling endpoint for bulk listing by trade and county if you need multiple contractors rather than a specific one.
Side effects
- License number not found — returned free of charge with an unknown status indicator
- Multiple name matches returned when searching by business name without city filter
- No matches found for the provided business name
- Invalid license number format (non-numeric or too long) rejected by schema validation
- CSLB registry temporarily unavailable causing lookup failure
