Crossconverts steamids between their variations(SteamID, SteamID64, SteamID3)
Doesn't support custom urls since I find that useless for my use
https://yourserver.com/convertID.php?id=YOURIDHERE
On successful conversion
{
"SteamID": "STEAM_0:0:736989607",
"SteamID3": "[U:1:1473979214]",
"SteamID64": "76561199434244942"
}
On invalid steamid
{
"error": "Invalid SteamID format"
}
On empty id param
{
"error":"ID parameter is missing or empty."
}
