Get Recommendations Endpoint Filters Request

[lisabscheibner]

I have a couple of use cases that aren't currently covered by the existing props and filters you can send to the get recommendations endpoint, so I figured I'd make a request

Filter by release date: if a user wants to listen to current music that sounds like music they listened to in the past, there's no way to request that. For instance, if I seed with Blink-182, I mostly get music from the late 90s/early aughts.

Filter out explicit: for kids or conservative users, it would be cool to allow users to filter out tracks marked as explicit.

Thanks for the consideration!
