Aicoo API

Layer 3: Aicoo OS + Tools

This layer handles persistent workspace state, notes, folders, todos, guest conversations, heartbeat automation, and tool execution.

Build on SharedOSAgent Network API

Layer Scope

Coordination, state, and execution

Aicoo OS is the operational surface around the core agent: workspace status, folders, notes, todos, conversations, and heartbeat runs.

Use it to sync product context, read back outcomes, and run predictable background coordination tasks.

It also exposes a tool bridge so external clients can discover and execute available Aicoo tools safely.

Bridges Both Tracks

Share links are documented under Build on SharedOS

The /v1/os/share endpoints are part of the workspace surface, but they double as the handshake entry point for network connections (/v1/network/connect), so their reference now lives in the SharedOS track.
