The Playground

The Playground is a developer console for Phantom. You point it at the chat API with your own API key, send turns with a fully editable persona, and inspect each turn live - the exact request and response JSON, the HTTP status, and the round-trip latency.

It's the fastest way to understand how a persona, the message buffer, and memory interact before you wire the API into your own backend.

The Playground console - connection and vector store on the left, chat in the middle, the request inspector on the right

Layout​

The console is three columns:

  • Left - configuration. Your connection (base URL + API key), your vector store, the persona, and per-turn options.
  • Center - chat. The transcript, per-reply badges, and the composer. Also the Retarget button for proactive openers.
  • Right - inspector. Two tabs: Live (the raw request/response) and History.

Getting in​

Open the Playground and paste in your credentials:

  • URL: playground.phantomrouter.ai
  • Set the base URL to the Phantom API (https://api.phantomrouter.ai).
  • Paste an API key with the chat:companion scope. See Authentication.
  • Configure your vector store in the left sidebar.

Nothing is sent anywhere except directly from your browser to the API you point it at - the key lives only in your browser's localStorage.
