STEAMID API

SteamID converter API

CS2.SPACE's GET /api/steamid/{id} converts a Steam custom profile name (the NAME in steamcommunity.com/id/NAME) or a SteamID64 into SteamID64, Steam32 (account ID), Steam2 (STEAM_0:X:Y) and Steam3 ([U:1:X]), and returns the player's name, avatar and profile URL.

Useful whenever users paste a profile link or a vanity name and you need the numeric ID other APIs expect.

What is the difference between SteamID64, Steam2 and Steam3?
