UNO Overlay API Skill

Work with overlays.uno overlay graphics powered by Singular.live. This skill covers all UNO apps, their API commands, and how to build integrations ranging from single HTTP calls to full control web apps.

When to Use

• Send commands directly to a UNO overlay (show/hide, set scores, update text, etc.)
• Build a Node.js, Python, or browser script to control overlays programmatically
• Create a web-based control panel for a UNO app
• Automate overlay updates from an external data source

How the API Works

Step 1 — Resolve the Token to an App

Before sending commands you need to know which UNO app the token belongs to. Fetch the app metadata:
