Inputs

Field	Type	Req	Default	Description
`query`	string	yes	`"22726"`	A CSLB license number (digits only, e.g. '22726') OR a name. Numbers are looked up directly. A name is searched against BOTH the business-name index AND the personnel/owner-name index, and the results are unioned (deduped by license #). For a person, enter 'First Last' (e.g. 'Phil Ransome') or 'Last, First' with a comma.
`includeDetails`	boolean	no	`true`	When on (default), each match is enriched with its full license record — entity type, issue/expiry dates, classifications, contractor's bond, and workers' comp. Turn off for a faster, lighter result list (license #, name, city, status only).
`maxResults`	integer	no	`50`	Cap on the number of matches returned (and enriched) in a single run. This is a lookup, not a bulk export — defaults to 50.
`proxyConfiguration`	object	no	`{"useApifyProxy":false}`	Optional. CSLB is usually reachable directly; enable a proxy (e.g. residential) only if a run is blocked or served a CAPTCHA challenge.

Pricing

Pay per result (dataset-item) — no charge for empty runs.
Example: 100 verified license records at $0.004/result ≈ $0.40.

FAQ

Where does the data come from?

The official California CSLB 'Check a License' registry — public, authoritative license data.

Can I find every license a person holds?

Yes — a name search matches both business names and owner/personnel records (RMO/RME) and dedupes, so you see every license that person is listed on.

What fields do I get?

License number, business name, status, classifications, issue/expiration, plus contractor's bond and workers' comp where CSLB publishes them.

How am I charged?

Pay-per-result — per license match returned. No charge for searches with no results.

Is this personal data?

It's public professional-license data (business and license-holder records as CSLB publishes them); we add no personal/PII enrichment.

How current is it?

It reflects the live CSLB record at lookup time.
