Just save this as karma.py and run it with Python 3.6 or higher.
import requests
import math
INSTANCE_URL = "https://feddit.de"
TARGET_USER = "ENTER_YOUR_USERNAME_HERE"
LIMIT_PER_PAGE = 50
res = requests.get(f"{INSTANCE_URL}/api/v3/user?username={TARGET_USER}&limit={LIMIT_PER_PAGE}").json()
totalPostScore = 0
totalCommentScore = 0
page = 1
while len(res["posts"])+len(res["comments"]) > 0:
totalPostScore += sum([ x["counts"]["score"] for x in res["posts"] ])
totalCommentScore += sum([ x["counts"]["score"] for x in res["comments"] ])
page += 1
res = requests.get(f"{INSTANCE_URL}/api/v3/user?username={TARGET_USER}&limit={LIMIT_PER_PAGE}&page={page}").json()
print("Post karma: ", totalPostScore)
print("Comment karma: ", totalCommentScore)
print("Total karma: ", totalPostScore+totalCommentScore)
MLem (the iOS Lemmy app) was also showing the user karma (but I think it was only showing karma gained on the local instance). So I guess this is nice for people that like to know their karma.
I also agree with @[email protected] that we should leave this as a thing for yourself. The Lemmy API should not bother with reporting user karma as It would be way too easy to cheat for people with singe person instances. (and of course the toxicity that comes with karma)
The API actually already reports something that looks like karma (it’s called post_score and comment_score for the user in question), but for some reason that value is quite off. Not sure why.
So for example, the post score that is reported for my user is ~20% lower than what you get if you sum all the post scores up, while the comment score is ~95% too low.
