Inputs

Field	Type	Req	Default	Description
`mode`	string	no	`"auto"`	auto (default): a licence number or name below runs a lookup, none runs the export. lookup: find licences by NSCB licence number or company / principal name. export: active licences by county and classification, names ignored.
`query`	string	no	`"Smith Electric"`	A Nevada NSCB license number (digits only, e.g. '0014202') OR a business name OR a person's name. Numbers are looked up directly; names search the company-name index by default. Use 'searchBy' to switch to principal/QI name search. Leave this and 'Search queries (batch)' empty to export every active Nevada licence instead, narrowed by the county and classification filters below.
`queries`	array	no	`["0014202","Smith Electric"]`	Look up many licenses in ONE run instead of starting a run per lookup. Accepts the same values as 'Search query' — license numbers, business names, or principal names, mixed freely. Combined with 'Search query' if you fill both, and duplicates are removed. Billing is unchanged: you are charged per matched record returned, not per query submitted.
`searchBy`	string	no	`"auto"`	Controls which NSCB index to search. 'auto' (default) routes digit-only queries to license-number lookup and everything else to company-name search.
`county`	string	no	—	Statewide export only. One of Nevada's 17 counties (Clark, Washoe, Carson City, Douglas, Elko, ...). A county search returns only Nevada-based firms in it; leave empty for every active licence, including out-of-state firms. An unrecognised county returns a free row listing the accepted ones instead of the whole state.
`counties`	array	no	`[]`	Several counties in ONE run. Combined with 'County' if you fill both.
`classification`	string	no	—	Statewide export only. An NSCB classification family code (A, AB, B, C-1 ... C-42, E-1, E-2; 'C2', 'C-2' and 'C02' are the same) or a word from its name, e.g. 'electrical', 'plumbing', 'roofing'. Empty = every classification. A firm is listed under its PRIMARY classification family.
`classifications`	array	no	`[]`	Several classification families in ONE run. Combined with 'Classification' if you fill both.
`includeDetails`	boolean	no	`true`	Search queries only. When on (default), each match is enriched with its full detail record: addresses, phone, business type, principals, qualified individuals, bond info, and dates. Turn off for a faster, lighter result list. The statewide export returns NSCB's listing row (street address, city, ZIP, phone, classifications, limit, expiry) and fetches no detail pages.
`maxResults`	integer	no	—	With a search query: cap on matches returned (and enriched) PER QUERY, not per run (default 50) — so a batch of 20 names cannot silently return only the first 50 rows overall and read as 'the rest don't exist'. A license-number query returns exactly one record regardless. Statewide export: cap for the whole run (default 500, a spend control). NSCB listed 19,186 active licences on 2026-10-09, so 100000 returns everything that matches; the run log states NSCB's own total beside what was returned.
`licenseTypes`	array	no	`[]`	Same as Classifications (NSCB's licence types are its classifications): a family code like C-2 or A, or a word like 'electrical', 'roofing'.
`statuses`	array	no	`[]`	Lookups: keep only licences whose NSCB status contains one of these words (active, inactive, revoked, expired...). The export lists active licences only; any other status there returns a free row saying so.
`status`	string	no	—	One status; same as Statuses.
`expiresAfter`	string	no	—	Only licences expiring on or after this date (YYYY-MM-DD). With 'Expires on or before' it lists licences due for renewal in a window. Works on exports and lookups.
`expiresBefore`	string	no	—	Only licences expiring on or before this date (YYYY-MM-DD).
`proxyConfiguration`	object	no	`{"useApifyProxy":true,"apifyProxyGroups":["RESIDENTIAL"]}`	NSCB intermittently drops license-search requests from Apify datacenter IPs, so this defaults to a residential proxy for reliable results. Bandwidth per search is tiny. You may switch it off to try datacenter IPs. The statewide export tries a direct connection first and uses this proxy only if NSCB does not answer.

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 Nevada State Contractors Board (NSCB) public 'ContractorLicenseSearch' portal — authoritative public-record data.

What can I search by?

A license number (digits only, e.g. '0014202'), a business name, or a principal/qualified-individual name. Use the 'searchBy' field to select the mode; 'auto' handles digit-only vs. name classification automatically. Leave the search empty to export active licences instead, filtered by county and classification family.

How big is a full export?

Measured 2026-10-09: 19,186 active licences statewide, 13,163 of them with a Nevada address. An export defaults to 500 rows; set maxResults to 100000 for everything. A county filter returns only Nevada-based firms in that county (Clark: 7,435); out-of-state licensees appear only in a statewide export. NSCB's listing covers active licences only — expired or revoked ones are reachable by a search query, not an export.

What fields do I get?

License number, business name, DBA, NV business ID, trade classification, status, city, and state always. With includeDetails on (default): full addresses, phone, business type, principals, qualified individuals, bond details, and dates.

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 NSCB publishes them on its public portal); we add no personal/PII enrichment.

How current is it?

It reflects the live NSCB record at lookup time — the same data you'd see on the public portal.
