Inputs

Field	Type	Req	Default	Description
`listCountiesOnly`	boolean	no	`false`	If true, skip the scrape and just return every valid California county name (from the live CSLB form) as the dataset. Free — not charged. Use this to look up the exact county spelling before running a real scrape.
`licenseClass`	string	no	`"C-10"`	CSLB classification code, e.g. 'B' (General Building), 'C-10' (Electrical), 'C-36' (Plumbing). Returns every active contractor holding this classification in the chosen county. Required unless 'Discovery Mode' is on.
`county`	string	no	`"Sacramento"`	Full California county name, e.g. 'Los Angeles', 'Sacramento', 'Orange'. Required unless 'Discovery Mode' is on.
`maxResults`	integer	no	—	Cap on the number of license records returned in a single run. Leave empty to return all matches.
`proxyConfiguration`	object	no	`{"useApifyProxy":false}`	Optional. CSLB is usually reachable directly; enable a proxy (e.g. residential) only if runs return no data because the IP is blocked.

Pricing

Pay per result (dataset-item) — no charge for empty runs.
Example: 500 C-10 electricians in Los Angeles County at $0.002/result ≈ $1.00.

FAQ

What does one run return?

Every active licensed contractor in the chosen California county for the chosen license class/trade — business, contact, classifications, bond, and workers' comp.

Where's the data from?

The official California CSLB registry — public license records.

How do I target a trade?

Use the `licenseClass` input (e.g. C-10 electrical, B general building, C-36 plumbing) plus the `county`.

How am I charged?

Pay-per-result — you only pay for the contractor rows returned, and empty runs are free.

Is this lead data compliant?

It's public, non-personal business-license data from CSLB — not consumer or PII data.

How fresh is it?

It reflects the live CSLB registry at run time.
