API calls to get list of all collaborative playlists given a genre, category, or keyword

[drewg2009]

I'm a pop punk artist who's also a software engineer looking to do something clever for the music community. But if Spotify could build it, it would make things way easier!

I am having a hard time finding playlists to submit my song to. Lots of playlisting platforms have high costs and often deliver bots on their playlists. Also it's hard to find curators from Spotify because there's no contact info shared unless it's in their playlist description. They don't respond often anyway, even when contacted. 

My goal is to leverage the Spotify API to build a small search engine for collaborative playlists. This way, people can work together to grow their playlists for free and like minded artists can grow their listenership together. Ideally if Spotify could provide this it would be way easier for me haha so I wouldn't have to build it the hard way.

Because collaborative playlists are not currently searchable within the Spotify UI, it would be nice to use the API to fetch all the playlists that have `collaborative: true` and display the username and possible contact info scraped from a playlists description to connect people. 

Maybe the app could also have a social aspect for people to network and grow playlists together. 

Is there an easy way to do this without having to crawl the Spotify database with a long running job and data collection from tracks? Ideally an endpoint to gather all playlists given a genre or keyword with the collaborative property would be the fastest way. 

Otherwise I would likely use the following search endpoint described in the docs to query in batches or small fetches at a time to slowly scan and collect the information, similar to how I imagine other search engines build out their search results. 

Would love if spotify built this feature within the app instead so I could focus on my music haha but happy to put my developer hat on if not.
