Game ID Checker API Docs

Real-time username lookup for 39 mobile games and live-streaming apps. One simple GET request per game — get a clean JSON back. This page covers everything you need: authentication, the response schema, every endpoint, and copy-paste samples in cURL, JavaScript, Python, and PHP.

Introduction

The Game ID Checker API takes a player's in-game user ID and returns the username associated with that account in real time. It's the same primitive that powers thousands of top-up shops, reseller bots, and community moderation tools — exposed as a single, predictable HTTP endpoint per game.

Every endpoint shares the same response shape so you only need to write your integration once. Add a new game, swap the path, and you're done.

Quickstart

Send a GET request to the endpoint for the game you want to check. Pass your API key in the x-api-key header. Here's a one-liner that verifies a Mobile Legends ID:

curl -H "x-api-key: YOUR_API_KEY" \
     https://api.neferbyte.com/game-id-checker/mobile-legends/1393323764/15748

const res = await fetch(
  'https://api.neferbyte.com/game-id-checker/mobile-legends/1393323764/15748',
  { headers: { 'x-api-key': process.env.NEFERBYTE_KEY } }
);
const data = await res.json();
console.log(data.data.username); // → "NeferKing"

import requests, os

r = requests.get(
    "https://api.neferbyte.com/game-id-checker/mobile-legends/1393323764/15748",
    headers={"x-api-key": os.environ["NEFERBYTE_KEY"]},
)
print(r.json()["data"]["username"])  # → "NeferKing"

<?php
$ch = curl_init("https://api.neferbyte.com/game-id-checker/mobile-legends/1393323764/15748");
curl_setopt_array($ch, [
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HTTPHEADER     => ["x-api-key: " . getenv("NEFERBYTE_KEY")],
]);
$res = json_decode(curl_exec($ch), true);
curl_close($ch);
echo $res['data']['username']; // → "NeferKing"

Authentication

Every request must include a valid API key in the x-api-key request header (lowercase or X-Api-Key — both are accepted). Keys are 32-character MD5 hashes issued when you subscribe.

GET /game-id-checker/mobile-legends/1393323764/15748 HTTP/1.1
Host: api.neferbyte.com
x-api-key: a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6

Getting a key

• RapidAPI — sign up at rapidapi.com/nazi436123/api/id-game-checker. RapidAPI keys only work on the RapidAPI gateway, not on the URLs in this doc.
• Direct (Telegram) — open @idgamecheckerbot, pick a plan, and the bot will send your key. This is the key to use here.

Base URL

All Direct-API endpoints share one base URL. Append the game slug, then the player ID (and server, where the game requires one).

https://api.neferbyte.com/game-id-checker/{game}/{id}/{server?}

• {game} — the game slug (e.g. mobile-legends). Slugs are case-sensitive.
• {id} — the player's user ID, exactly as the player would type it in-game.
• {server} — only required for some games (e.g. Mobile Legends server, Valorant tag).

Response schema

Every successful response has the same shape, regardless of which game you queried. Just three fields inside data: game, userId, username.

Success — 200 OK

{
    "success": true,
    "data": {
        "game": "Mobile Legends",
        "userId": "1393323764",
        "username": "NeferKing"
    }
}

Error

{
    "error": true,
    "msg": "Can't find a username for \"User ID: 99999\"."
}

Field reference

Errors

Errors are flat JSON with error: true and a msg field. Common cases:

Rate limits

Each plan has a fixed daily request budget. The counter resets at 00:00 UTC. When you hit the cap you'll get the You have reached your daily limit today. error. Plan tiers and exact quotas are listed inside @idgamecheckerbot under /plans, or on the RapidAPI listing.

There is no per-second rate limit beyond the global anti-abuse layer — but treat each lookup as if it costs upstream bandwidth (it does). Cache results in your own database when possible.

Testing your key

The fastest way to confirm your key works: query Mobile Legends with a known-good ID. If you get a username back, you're set.

curl -H "x-api-key: $YOUR_KEY" \
     https://api.neferbyte.com/game-id-checker/mobile-legends/1393323764/15748

Stale slugs corrected (CoD-mobile→cod-mobile, pubg-lite→pubgm-lite, free-fire-global→ff-global); deprecated games (Point Blank, Royal Dream, Mico Live, Nimo TV, Likee, 4Fun, and other chat apps that are no longer routed) removed; BGMI, PUBG Mobile Global, Honor of Kings, Genshin Impact, Blood Strike, Arena Breakout, MU titles, Dragon Raja, LifeAfter, NIKKE, Eggy Party, Whiteout Survival, Ace Racer, Speed Drifters, MCGG, DFM, and Bigo Live added.
• 2025-05-06 — Earlier rewrite to the current Direct API surface (unified error/status/msg/data schema).
• 2025-04-29 — game-id-checker rewrite layer added; all endpoints now path-based instead of ?game= query.
• Earlier — Legacy schema (error/status/msg/data{id,avatar,username}) deprecated. The current schema has no avatar field.
