Current Business License Prospects
Query current business-registration records directly from official Chicago and San Francisco open-data APIs. Results include source-dataset and source-record links; this product does not claim private emails or buyer intent.
Preview request
The preview path is rate-limited and does not charge. Production requests use the same parameters and return a standard x402 challenge when no payment signature is present.
