In Facebook Marketing API, how can I get the estimated audience size by a combination of demo standard? Which endpoint should I use and how to write the html get request?
For example, I want to know how big is the audience size of people who live in US, age between 14-35, female, interest in {baseball,...}
I see that on this page: https://developers.facebook.com/docs/marketing-api/targeting-search/v2.9
you can get the audience size within one specific interest, but I want to know the audience size within a combination of conditions.
