Key Authentication Integration (Lua)

Easily integrate our robust key system into your scripts. Load the API library directly from our servers, verify the user's key, and execute the protected script.

-- 1. Load the API Library from our servers
local api = loadstring(game:HttpGet("http://luatiger.kro.kr/Library.lua"))()
--> Returns a table with methods that you can use.

-- 2. Initialize it with your Project ID and Script ID
-- You can find these in the dashboard under the Projects and Scripts sections.
api.project_id = "YOUR_PROJECT_ID_HERE"
api.script_id = "YOUR_SCRIPT_ID_HERE"

-- 3. Make the API request to check the key
local script_key = "USER_INPUT_KEY_HERE"
local status = api.check_key(script_key)

-- 'status' returns a table: {code: <string>, message: <string>, data?: <table>}
print(status.code)

-- 4. Custom Logic based on authentication result
if (status.code == "KEY_VALID") then
    -- Fetch basic info about the key (only available if KEY_VALID)
    -- auth_expire is a UNIX timestamp. We subtract os.time() to get seconds left.
    local seconds_left = status.data.auth_expire - os.time()
    print("Welcome! Seconds left: " .. seconds_left)
    print("Total executions: " .. status.data.total_executions)
    print("Is key from ad system? " .. (status.data.note == "Ad Reward" and "YES" or "NO"))
    
    -- Execute the script based on the script_id you put above.
    api.load_script()
    return
    
elseif (status.code == "KEY_HWID_LOCKED") then
    print("Key linked to a different HWID. Please reset it using our bot.")
    return
    
elseif (status.code == "KEY_INCORRECT") then
    print("Key is wrong or deleted!")
    return    

elseif (status.code == "KEY_EXPIRED") then
    print("Your key has expired!")
    return
    
elseif (status.code == "EXECUTION_CAP_REACHED") then
    print("You have reached the maximum execution limit for this key.")
    return
    
else
    -- Fallback for anything else (e.g., blacklisted, rate-limited, emulator blocked)
    local player = game:GetService("Players").LocalPlayer
    player:Kick("Key check failed: " .. status.message .. " | Code: " .. status.code)
end
