Locate the 'Active Home Improvement Contractor Licenses' dataset on NYC Open Data and note its Socrata resource identifier.
Query the dataset's SODA API JSON endpoint, filtering by business name or license number using the $where/$q query parameters.
Parse the returned records for license status, license number, and expiration date to confirm the subcontractor is currently licensed.
Register for a free Socrata app token and include it on requests to get a higher rate limit than anonymous access.
Re-check the dataset periodically for renewals close to the crew's project timeline, since licenses can lapse mid-contract.
Known gotchas
This dataset is scoped to NYC-licensed Home Improvement Contractors specifically; it won't cover subcontractors licensed only in a different city/state, or businesses that don't fall under that license category.
Anonymous (no app-token) requests are subject to lower Socrata throttling limits and can get rate-limited during bulk checks.
