We’re launching the Omega Crafter API beta on the Omega Crafter beta branch!

Use any programming language to call the API and control in-game elements like Grammi from outside the game, enhancing your Omega Crafter experience.

Note

• This feature is currently in beta and is provided as is, with no guarantees of functionality or compatibility.

• We strongly recommend that you back up your save data and use this feature at your own risk.

• The API can only be called from your local PC and does not support multiplayer.

• Because this feature is still under development, the documentation and API responses are currently available only in Japanese.

Detailed instructions for enabling this feature are provided at the end of this announcement.

Basic demo: Running a simple script (Python)

Advanced demo: Controlling multiple Grammi units (Python)

With code-driven control, you can build flexible logic using variables and functions, improving both functionality and reusability.

Advanced demo: Using AI agents

This demo accepts player commands such as “Craft 3 stone axes” and completes the task by orchestrating one manager Grammi and two worker Grammi units.

Demo: Using the documentation UI (Swagger UI)

The API specifications are available in the HTML documentation included with the game. Because it uses Swagger UI, you can interactively test the API directly on the page. You can also view the documentation directly on this page.

How to switch to the beta branch

Step 1: Open Settings (gear icon) > Properties.

Step 2: Under Betas > Beta Participation, select the api-experimental branch.
