How this service works
Search for companies using filters passed in the request body. Returns an array of numeric Coresignal company IDs (e.g., [4744382, 1635599, ...]). Use these IDs with the 'Base Company Collect' endpoint to get full company profiles. All filters are optional; combine any number of them to narrow results.
Output
An array of numeric Coresignal company IDs matching the specified filter criteria, which can be used as inputs to company enrichment endpoints for full profile data.
Example use cases
Example prompt
“Search Coresignal for technology companies headquartered in the United States with between 50 and 500 employees that were founded after 2010 — I need the list of company IDs so I can enrich them afterward.”
Technical details
Endpoint
POSThttps://mpp.orthogonal.com/coresignal/v2/company_base/search/filter?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover companies matching specific firmographic criteria (industry, location, size, founding year, etc.) and want to retrieve their Coresignal IDs for subsequent enrichment. Prefer this over the Preview endpoint when you need actual IDs rather than summary data, and over direct enrichment when you don't already know the company's domain.

- No matching companies returns an empty array
