I love the API documentation, and I'm really digging the ability to fetch Spotify's advanced data about songs directly. It's amazing to have data about so many songs in a structured way!
I'm wondering if it's feasible to search by any of these attributes of a song? It'd be awesome to be able to search for songs in a particular key/tempo for some research I'm looking to do.
If it's not possible today, is it something that could potentially be on the roadmap?
There is the Get Recommendations endpoint which allows you to get recommendations based on those kind of values with the Tuneable Track attributes, there's one for key and tempo for example.
