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 (e.g., [4744382, 1635599, ...]) matching the provided filter criteria. These IDs can then be passed to the Coresignal Base Company Collect endpoint to retrieve full company profile data.
Example use cases
Lead list by industry and size
“Give me a list of Coresignal company IDs for financial services companies in the United States with at least 200 employees — I want to build a prospect list from their full profiles.”
Competitor discovery by domain
“I want to find the Coresignal ID for Stripe — can you search by their website domain stripe.com so I can pull their full company profile?”
Market research on recent startups
“Search for technology companies founded between 2018 and 2023 with fewer than 500 employees in the United Kingdom and give me their Coresignal IDs so I can analyze them.”
Technical details
Endpoint
POSThttps://x402.orthogonal.com/coresignal/v2/company_base/search/filterWhen to prefer
Use this endpoint when you need to discover companies matching specific firmographic criteria (industry, country, size, founding year) and want Coresignal company IDs to retrieve full profiles. Prefer this over direct name lookup when you need to find multiple companies matching a profile rather than a single known company, or when building prospect lists, market maps, or competitive analyses based on structured filters.
Side effects
- No matching companies found for the given filters — returns an empty array
- Invalid filter values (e.g., non-existent country name or industry string) may return empty results or an error
- Rate limiting or payment failure (x402) may prevent the call from completing
- Overly broad queries with no filters may time out or return excessively large result sets
- Misspelled company names or domains may return zero results
