Current Business License Prospects
Find current official business-registration leads from 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. It executes the live source and returns the paid response shape while withholding decision-ready values. Production requests use the same parameters and return a standard x402 challenge when no payment signature is present.
curl --request GET \ "https://ai-data-marketplace-1042299154756.us-central1.run.app/api/v1/leads?preview=true&city=Chicago&query=auto&limit=20"
Input contract
| Parameter | Type | Required | Description |
|---|---|---|---|
city | string | No | Chicago or San Francisco. Omit to search both official sources. |
query | string | No | Case-insensitive keyword matched against available business name, owner, address, and activity fields. |
limit | integer | No | Number of current registrations to return, from 1 to 50. |
Example deliverable
This is the documented response shape, not a promise that live values will match the example. The paid request returns current or declared-source results using the same contract.

}Why this offer exists
Current official Chicago and San Francisco business-registration prospects with source links.
Buyer searches: business leads, business registrations, local prospecting, new business research.
Why pay: Receive the complete current result without maintaining the upstream integration.
Launch price: 0.01 USDC per complete paid result. The live contract proof verifies source, freshness, inputs, and response shape before a wallet is asked to pay.
Purchase decision
Buy when: the active task needs this product's structured result, its declared source and freshness are sufficient, and 0.01 USDC is within the buyer's authorized per-request limit.
Skip when: a cached result is sufficient, the source or fields do not satisfy the task, or the buyer has not authorized payment. Do not bypass wallet, budget, or user-approval policy.
Guaranteed response metadata
Every successful product response identifies how the result was produced. Product-specific output fields are documented in the paid OpenAPI contract. The preview proves the live source and field types without returning the paid values.
