Count Mode You can get the total number of results matching any filter combination without consuming credits by adding count=true to your request. This returns an empty data array with full pagination metadata, including totalCount.
curl -X GET "https://www.trysignalbase.com/api/v2/signals/acquisitions?count=true&countries=US,GB&date_preset=last_90d" \ -H "Authorization: Bearer YOUR_API_KEY"
Response: { "success" : true , "data" : [], "pagination" : { "currentPage" : 1 , "totalPages" : 8 , "totalCount" : 152 , "hasNextPage" : true , "hasPreviousPage" : false }, "meta" : { "endpoint" : "signals.acquisitions" , "creditsUsed" : 0 } }
Use count mode to preview how many results match your filters before fetching actual data. This is useful for building filter UIs, showing result counts, or validating queries — all at zero credit cost.
