Quickstart

From API key to a spoken reply

Create a project key in the dashboard, install the SDK, and stream one turn over the Realtime WebSocket.

1. Get a key

In hub.kupe.in open a project and create an API key. It looks like sk-kupe-... and is scoped to that org and project. Export it (and optionally override the API host):

2. Install

3. Mint a session and connect

GET /v1/me fills in org_id / project_id for API keys, so the SDK constructor can be just Kupe().
The WebSocket speaks OpenAI-compatible JSON. Audio is PCM16 mono at 24 kHz. See Realtime for client and server events.

4. List your agents

Try it in the docs

Every REST endpoint in the API reference tab has an interactive playground. Paste sk-kupe-YOUR_KEY into the Bearer field — requests go to https://x.kupe.in. See API playground.
Coding agents can call the same API over MCP. Install once with http://mcp.kupe.in/mcp — see Kupe MCP.
