Legacy helpers still mounted#

http
GET /{userid}/basic
GET /{userid}/solved
GET /multi/{userids}
GET /users/common-contests/{userids}
GET /contests/upcoming

userids is semicolon-separated (tourist;Petr). Commas are accepted and rewritten.

/contests/upcoming?gym=true includes gym contests.

These five are deprecated=True in OpenAPI. They still return useful data CodeTrace’s detail page uses. Canonical card composition should go through /{userid}/profile and /{userid}/contests.
