@igorskh, could you tell me where you took that API screenshot? I have previously searched for documentation on Duolingo's API, but had little success. What you have in that screenshot is certainly the kind of thing I would be interested in looking at.

@golmschenk I have a repo with openAPI docs https://github.com/igorskh/duolingo-api

Hi @saltedlolly,

It is possible with duolingo API, but this package doesn't implement this method.

The endpoint is www.duolingo.com/users/{userID}/xp_summaries

It returns an array for the given time range, as following:

Hope it helps.

Thanks - this is just what I have been looking for! Unfortunately, I'm struggling to make it work. Could you possibly provide me with an example query? Sorry, I'm quite new at this.

I tried https://www.duolingo.com/users/6364229/xp_summaries?startDate=2022-02-16&endDate=2022-02-17&timezone=Europe/London but got nothing.

[igorskh]

Sorry, my bad. The URL should be https://www.duolingo.com/2017-06-30/users/6364229/xp_summaries?startDate=2022-02-16&endDate=2022-02-17&timezone=Europe/London

The 2017-06-30 is missing. It's just a fixed prefix Duolingo currently use for their API endpoint.

Example:

GET /2017-06-30/users/6364229/xp_summaries?startDate=2022-02-16&endDate=2022-02-17&timezone=Europe%2FLondon HTTP/1.1
Authorization: Bearer <your_jwt_token_here>
Content-Type: text/plain; charset=utf-8
Host: www.duolingo.com

"summaries":[{"gainedXp":87,"frozen":false,"streakExtended":true,"userId":6364229,"dailyGoalXp":50,"date":1645056000,"repaired":false},{"gainedXp":null,"frozen":true,"streakExtended":false,"userId":6364229,"dailyGoalXp":null,"date":1644969600,"repaired":false}]}

Amazing! Exactly what I needed! And even better it seems I don't even need to be authenticated. Many thanks.

[igorskh]

You're right, it works even without Authorization header or cookies, didn't realize that before.

[saltedlolly]

Thanks for all your help. As an aside, is there a query I can make to return the userid of a provided username?

[igorskh]

Yes, there is an endpoint which returns user information by username, it contains among other fields the userID:

https://www.duolingo.com/2017-06-30/users?username=<username>

e.g.:
https://www.duolingo.com/2017-06-30/users?username= igorskh returns

{
    "users": [
        {
            "joinedClassroomIds": [],
            "streak": 1873,
            
            "id": 14397890
        }
    ]
}

Lot's of other things as well, but you can get ID from here.
