What this page answers
Page-specific proof
Windsurf + unlimitedcodex OpenAI-Compatible API combines 3 setup steps, 4 buyer constraints, unlimitedcodex delivery, limits, pricing, and setup guidance, and related answer sources instead of a generic integration blurb.
Verification path
After manual delivery, verify Windsurf with GET /v1/models, one tiny chat/completions request, and endpoint-specific image or embedding checks before long runs.
Decision summary
Best fit
Windsurf 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 Windsurf with /v1/models and one small request before long runs.
Setup steps
Step 1
Confirm provider settings
Check whether your Windsurf workflow exposes custom OpenAI-compatible base URL and API key settings. If the client hides provider configuration, use an adapter or supported integration path.
Step 2
Use delivered credentials
After manual setup, use the delivered base URL, API key, setup files, and model IDs. Do not guess model IDs before delivery.
Step 3
Run a small edit task
Test one small code edit, one failed-test repair, and one retry-heavy task before moving a full project into the workflow.
