I am confused whether we should create separate API for fetching result and result-count OR we should fetch count based on query string in the result API only.

/api/results/ : Fetches all records
/api/results/?city=1: Fetches all records with city=1
/api/results/?iscount=1: Fetches the count of records i.e. list of cityId and count of record for respective cityId
/api/results/?city=1&iscount=1: Fetch the count of record for cityId=1

OR 

/api/resultcount/: Fetches the count of records i.e. list of cityId and count of record for respective cityId
/api/resultcount/?city=1: Fetch the count of record for cityId=1

To me query string is used for filtering of resource so, I am in favor of creating separate API for fetching the counts. Opinion?

We don't need to create another point for fetching the count. Instead, we can send the count details in the response header.

It will be something like below,

/api/results/(GET method) - This will return the results.

/api/results/(HEAD method) - This will just return the results count in the response header.

Please take a look at the following link

    The problem with the `HEAD /api/results` is that the server-side query will have to actually fetch the results, when all you want is a count (less intensive query). – pedromorfeu Nov 30 '18 at 12:48
