I am working on a website based around the gimmick of knowing who the user is already on the first visit to the site. So I want to use JavaScript to query some advertising API to get the information they already have about the user coming in. Is this possible?

For instance, if I can get the advertising ID (by finding the associated cookie on my website) that Google (or anyone else) has put there with the ad, is it possible to access what Google thinks the user is interested in? That is, given the advertising id, is their an API I can call to get the info google says they have about them? Like how I can tell what they think about me by going to https://adssettings.google.com/authenticated, can I do that for any user automatically? Information like "Likes football, volleyball, coding"?

Ideally this would be done via an HTTPS request via Javascript or some Javascript API.
