I figured there had to be an easier method of getting apk packages to the FTV without installing them on a separate device first and then pulling the package from it.
Just put the URL of the package into the field and it will generate a link for you to download directly. No need for your Google ID or anything.
Interestingly enough I came across this same site when looking for ways to get apk files to try on my FireTV. They have always hit their download limit when I've tried a direct download, however if that happens their Chrome extention works well and is safe (although if you are like be and use OTP with your Google account, you will need to create an application specific password, which is actually a good idea in terms of safety). Once the extension is configured correctly there will be an additional icon in your address bar when you visit play.google.com that will let you download the apk of whatever free Google App Store page you are on.
