Where it goes
Is Data API required on the client, server, or both?
The project page does not say whether this file belongs on the client, dedicated server, or both.
The source does not explicitly classify this release as client-only or server-only.
What else does Data API 26.1_v1.10.3 need?

Install Fabric API first. We found matching files for this game-version and loader setup.
