Roo Code (gateway)

Route Roo Code’s LLM calls through the Respan gateway for automatic logging, caching, and model switching. Roo Code has a built-in OpenAI Compatible provider, so only your RESPAN_API_KEY is needed.

Setup

1

Install Roo Code

Install the Roo Code extension from the VS Code Marketplace, then open it from the sidebar.

2

Configure the OpenAI Compatible provider

  1. Click the gear icon to open Roo Code Settings.
  2. Under API Provider, choose OpenAI Compatible.
  3. Fill in the fields:
    • Base URL: https://api.respan.ai/api
    • API Key: YOUR_RESPAN_API_KEY
    • Model: gpt-4o
  4. Save.

No separate provider key needed. The Respan gateway handles provider authentication.

3

Start coding

Open the Roo Code chat panel and send a message. All LLM calls now route through Respan.

Switch models

Change the Model field to use any of the 250+ models available through the gateway.
