Page-specific proof
Roo Code + unlimitedcodex OpenAI-Compatible API combines 4 setup steps, 4 buyer constraints, official reference docs plus unlimitedcodex delivery, limits, and setup guidance, and related answer sources instead of a generic integration blurb.

Decision summary
Best fit
Roo Code teams that can use a custom OpenAI-compatible base URL and want ChatGPT 5.5 Ultra and Codex API access after manual delivery.
Not a fit
Not ideal when you need instant self-serve provisioning, an official OpenAI account, or production traffic beyond 4 concurrent connections.
Next step
Complete checkout, wait for the setup email, then verify Roo Code with /v1/models and one small request before long runs.
Setup steps
Step 1
Complete checkout and wait for setup
Choose Unlimited Weekly or Monthly, complete Stripe checkout, and wait for manual delivery of the API key, base URL, setup files, activation date, start date, and end date.
Step 2
Open Roo Code provider configuration
Select the OpenAI Compatible provider path in Roo Code, then confirm the exact mode you plan to run accepts a custom base URL, API key, and model ID.
Step 3
Enter delivered unlimitedcodex values
Use the delivered /v1 base URL, Bearer API key, and ChatGPT 5.5 Ultra or Codex model ID from setup delivery. Do not guess model IDs before the setup email arrives.
Step 4
Verify tool behavior before a repo run
Run /v1/models, one tiny chat request, and a small Roo Code task. Check native tool-calling behavior, retries, model selection, and queue pressure before a long autonomous loop.
Example configuration
Provider: OpenAI Compatible Base URL: <delivered unlimitedcodex /v1 URL> API key: <delivered API key> Model ID: <delivered ChatGPT 5.5 Ultra or Codex model ID> First checks: /v1/models, one tiny chat request, then one small Roo Code task.
