How this service works

Find previously unknown businesses or locations with recent license, permit, inspection, ownership, opening, closure, or tenant-transition signals. Use for market research, sales prospecting, expansion tracking, and location intelligence. Results are compact by default and always distinguish regulatory leads from confirmed public status.

Output

A paginated list of compact (or standard/full) business-change event records, each distinguishing regulatory leads from confirmed public status, including event type, business/location identity, geography, industry, and a cursor for fetching the next page.

Example use cases

Restaurant Sales Prospecting in Metro Area

“Show me up to 30 new restaurant or food service businesses that have gotten opening permits or licenses in Los Angeles in the past 90 days — I'm looking for leads for our equipment leasing sales team, use standard detail.”

Commercial Real Estate Tenant Transition Tracking

“Find operator changes and tenant transitions in retail locations across zip codes 10001, 10002, and 10003 in New York — I want to spot vacancies and new tenants for our commercial brokerage, limited to the last 60 days.”

Construction Activity Monitoring for a Sales Territory

“Search for construction activity and remodel signals within 50 km of Austin, TX for any industry — observed after January 1 2025 — and give me up to 100 results so I can identify prospects for our contractor supply business.”

When to prefer

Use this endpoint when you need to discover new or recently changed businesses across a geographic area using intent-based filters (openings, closures, permits, construction, operator changes). It is the right starting point for prospecting workflows before using the sibling evidence-expansion or premises-detail endpoints. Prefer it over general web search when you need structured, regulatory-signal-backed business change data rather than unstructured web results.
