As requested in the community forum I'm filing a bug request regarding new API endpoint:

https://community.metabrainz.org/t/what-do-you-want-in-listenbrainz/444888/49?u=karaluh

I would like to update the music player database with play count from LB to have:

1. the correct playcount when scrobbling from different players/devices,
2. a backup in case of broken/lost player database.

To achieve this with the current API I have to get the complete listen history which is a lot of API calls. If LB would provide the calculated play count per track it would make my life much easier. And since you already have this info because there's "top recordings for user" endpoint it shouldn't be too hard to do, right?

Also, last.fm exposes this in its API:
