Hi, I have a problem. I cant get results from all rounds from tournament. When I call:https://api.chess.com/pub/tournament/krakw---polish-chess-tour-1837419 In rounds section I got only 1 url: "rounds":["https://api.chess.com/pub/tournament/krakw---polish-chess-tour-1837419/7"]When I call for example: https://api.chess.com/pub/tournament/krakw---polish-chess-tour-1837419/1I got empty results. How get rounds 1,2 etc?

Hi all, Is there an API I can call that will show me historical puzzle stats, i.e. the daily Attempts / Passed / Failed history one can see on the Stats --> puzzles graph? If not a direct API is there any other mthid I can use to access? BVC

I don't know why my puzzles score was decrease too much but not have the reason. It happened at 07/10/2025. So please give back to me soon

Would be possible to share in this API some internal player id and enable to call this API through this player ID? The problem with the player name field is that players change the names time to time and then it is not possible to link old and new profile, so it will duplicate the player.

Hi everyone, I recently noticed that my puzzle Elo dropped dramatically—from over 3000 to around 1700! I’ve been doing puzzles regularly in the past, but I haven’t solved many in a while. I’m wondering: ---Can a long break from puzzles cause such a big drop? ---Are there other factors that could affect puzzle ratings? I’d really appreciate any insights or advice. Thanks in advance!

https://api.chess.com/pub/player/maska_x/matches {"status":"error","message":"Internal Server Error"} I also notice the part of the message to report in forums has been removed. Are we now supposed to use the support bug report? If so another reduction in the API facility.

Hi guys,  I made a website to show titled players game streaks that are "interesting" based on the probability of such streaks occurring (a player winning too many unlikely games in a row). The site is hosted on AWS as a static website and I use chess.com python module to scrape the information (following the TOS, only one request at a time). I have the repo on GitHub open for everyone. Please check it out, I hope it can help someone in their personal projects. Maybe even give it a star(or two tell a friend!).https://github.com/OscarGarciaF/InterestingChess https://www.interestingchess.com/

It's offtopic but probably interesting to see for other developers, too. https://drive.google.com/file/d/1o7SCX2kEiEPqsXN3GVkzEDPMtYqklnqr/view?usp=drivesdk Opponent doesn't time out at 0.0s and is granted bonustime instead in bullet 1 minute, and I was very lucky that I screen recorded the game. In the game review it looks as if he never reached 0.0 Of course you cannot know whether I faked the video. (I did not.) https://www.chess.com/analysis/game/live/143369117936/analysis?move=64

I have beaten the 5 holiday bots but didn’t got the achievements and even though I contacted the support team they didn’t fixed it

Note: This was previously posted on the Chess.com Beta Club, and they sent me here Hey! I do (web)development stuff for fun and am a Twitch mod for a few Chess.com partnered streamers and I've noticed viewers like stats. They like to use !whois and !stats commands on Twitch to view stuff about Chess.com users. Recently, player accuracies were a topic in one of the streams. I figured it would be cool to create an accuracy command that calculates a player's average accuracy in the last month or so (that way, we wouldn't have to get, you know, ALL games someone's ever played). I was disappointed to find out that the Published-Data API does not have give us this information My suggestion would be to add each player's accuracy to the API for games that have previously been analyzed (e.g. only games where accuracies are already known). My personal use for this would be to make fun Twitch chat commands, but I'm sure other developers would find other uses for it as well! I'd love to hear how you guys (and especially a Chess.com developer) feels about this! Thanks in advance!

Hi All - I’ve built a new tool called www.ChessCorrection.com that connects your recent Chess.com games with your owned Chessable courses. The site scans through your games and shows you when a position matches a line in your repertoire. With one click, you can jump straight into the exact spot in your Chessable course, complete with the author’s commentary, recommended moves, and follow-ups. What makes this especially valuable is when your move isn’t in the course. Instead of wondering if it was playable or a mistake, you can immediately see what the course teacher suggests and why. It’s a fast way to identify gaps in your repertoire, strengthen your openings, and ultimately boost your rating. This also lets you focus your MoveTrainer study on the exact lines you’re actually encountering in your games, helping you avoid repeating the same mistakes in the future. The site is built using the public APIs that are available here and I'd love to get any feedback or find out whether anyone is encountering issues. Thanks to support from the Chess.com team I was able to add the ability to sign in with your Chess.com account. Thanks, Brett
