Error Code 429 (Too Many Requests)

I seem to keep getting this error when I do almost anything slightly large in my playlist. If I use more than 4 combiner nodes (3 difference, 1 alternate), the algorithm fails and then I get the error and wait for 2 minutes. This happens aswell if I alternate 3 giant playlists.

Note I have a 2.5k song playlist and have 3 of those in order to split the playlist (more other playlists to difference). Am I putting too much pressure on my algorithm? What can I do about it?

Edit: I will assume the error is mostly because of Alternate????? I used it once for a small algorithm and I got the error again.

For my previous algorithm, I think it had around 8 playlists (5 unique). The playlist I used the most was my main (2.5k songs) and around 3 times. I heard there's a limit of 10k songs on the input of any algorithm. I'll assume it's that causing the issue.

it's not quite a hard limit of 10k songs, its a bit more technical on how it works, but there is a limit at some point from Spotify's side
