HMTAPI

Turn your Minecraft server into a REST API.

HMTAPI exposes your Paper server over plain HTTP and returns JSON. You pick the contents of each endpoint in a small YAML config and can pull in live data from any PlaceholderAPI placeholder — player balance, rank, online status, and so on.

// GET /api/users/Notch
{
  "username": "Notch",
  "last_login": "2026/09/25 22:13:20",
  "balance": "1250.42"
}

Features

• Simple YAML config. No code needed — just define the endpoints you want.
• Any data you want. Combine built-in placeholders with any PlaceholderAPI placeholder.
• Per-player and global endpoints. Serve server-wide data, or data about one specific player.
• Reload without restart. Update your config in-game and apply it immediately.
• Safe by design. API traffic never blocks the server's main thread.
• No bloat. No bundled libraries, no database, no metrics to maintain.

Quick start

1. Install PlaceholderAPI — it is a hard requirement.
2. Drop the HMTAPI jar into your plugins folder.
3. Start the server once to generate plugins/HMTAPI/config.yml.
4. Edit your endpoints.
5. Run /hmtapi reload in-game. No restart needed.

endpoints:
  users:
    require_player: true
    object:
      username: "{username}"
      last_login: "{last_login}"
      balance: "{papi:%vault_eco_balance%}"

Then try it out:

curl http://localhost:4567/api/users/Notch
