What this page answers
Page-specific proof
Cline + 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.
Verification path
After manual delivery, verify Cline with GET /v1/models, one tiny chat/completions request, and endpoint-specific image or embedding checks before long runs.
Decision summary
Best fit
Cline 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 Cline 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 Cline provider settings
In Cline, choose the OpenAI-compatible or custom provider path for the workflow you want to run. Confirm that this exact path accepts a custom base URL.
Step 3
Enter delivered API details
Paste the delivered unlimitedcodex /v1 base URL, API key, and ChatGPT 5.5 Ultra or Codex model ID from setup delivery. Do not guess model IDs before delivery.
Step 4
Run a small agent task first
Start with /models or a tiny chat request, then run a small repository task before long autonomous loops so you can check auth, model selection, retries, and the 4-connection boundary.
Example configuration
Provider: OpenAI-compatible Base URL: <delivered unlimitedcodex /v1 URL> API key: <delivered API key> Model: <delivered ChatGPT 5.5 Ultra or Codex model ID> Smoke test first: /models, one tiny chat request, then a small Cline task.
