How to Use MLBB Public Data API Web Project

Step 1: Open the Website

Visit https://mlbb.rone.dev. On the home page you will see two options: Open Demo Website and Open API Docs. Start with Open Demo Website if you want the guided interactive flow.

Step 2: Sign In First (Mandatory for User Endpoints)

Click Sign In in the navbar, then fill Role ID and Zone ID. Click Send VC. A verification code is sent to in-game mail and expires in 5 minutes.

• Without sign-in, user endpoints can fail or return unauthorized responses.
• This applies to both web endpoint execution and API docs authorization.

Important: User endpoint routes are designed for authenticated usage. Always complete login and keep JWT available.

Step 3: Login with VC

In the same popup, enter VC and click Sign In. On success, navbar shows your avatar, username, and country. Open account panel to view roleId (zoneId) and copy JWT.

Step 4: Execute Endpoint Requests

Choose a group and endpoint. For example, MLBB hero detail. Fill required parameters like hero_identifier (numeric ID or normalized name), plus optional size/index/lang.

Step 5: Read Responses and Export Snippets

After execution, use snippet tabs (curl, python, javascript, go, node, php, java, csharp) and copy actions. Inspect Readable Response with the view-mode switch, then verify raw JSON if needed.

• Key-Value mode is best for object inspection.
• Key As Header mode is best for compact table-style scanning.

Step 6: Optionally Use API Docs

If you prefer Swagger UI, open API Docs from home. For user endpoints, authorize with Bearer token using JWT copied from navbar.

Step 7: Paste JWT for API Docs Authorization

In the API docs, click Authorize. Paste JWT in the Bearer token field. After successful auth, you can execute user endpoints directly from the docs interface.
