People who do web-scraping or use the internal APIs are basically doing so at their own risk. Leago has told us that the APIs are subject to change and there is NO SUPPORT for people trying to use them, because US Chess doesn’t have that expertise on staff and Leago can’t afford to do it for free, so they’d either need to bill US Chess for that time or bill the programmers directly.
Is there at least documentation for the APIs? I’m sure there are quite a few developers on here that would like access… and can undoubtedly help USCF with questions.
Yes, there is some documentation for the APIs.
Send email to mnolan@uschess.org and I’ll send it to you. (That’s so I have a list of who’s asked for it, as we might find that a useful list of players with some IT expertise.)
