Windsurf custom base URL, OpenAI-compatible API setup, and package-specific Codex model access questions.
Integration
Use unlimitedcodex as the API access layer behind Windsurf-style coding workflows.
When your editor or agent stack supports an OpenAI-compatible provider, compare package-specific model families on /pricing before testing the delivered setup.
- OpenAI-compatible base URL checklist
- Exact model IDs from the setup email and authenticated GET /v1/models
- GPT-5.5 XHigh at $19/week or an eligible $59 first month followed by $69/month; GPT-5.6 Sol at an eligible $69 first week followed by $89/week, or a $179 first month followed by $199/month
- Unlimited token consumption with 4 concurrent connections
Quick answer
Plan Windsurf with delivered OpenAI-compatible access: XHigh $19/week or $59→$69/month; Sol $69→$89/week or $179→$199/month. One welcome price per account.

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, use the setup email and authenticated GET /v1/models to verify Windsurf, then run one tiny chat/completions request and any supported image or embedding checks before long runs.
Decision summary
Best fit
Windsurf teams that can use a custom OpenAI-compatible base URL and choose GPT-5.5 XHigh at $19/week or an eligible $59 first month followed by $69/month, or GPT-5.6 Sol at an eligible $69 first week followed by $89/week, or a $179 first month followed by $199/month.
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
Compare the package families on /pricing, complete checkout, then use the setup email and authenticated GET /v1/models to verify Windsurf before one small request.
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 and key, then verify the exact model ID with the setup email and authenticated GET /v1/models.
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.

FAQ
Is unlimitedcodex a Windsurf product?
No. Windsurf is an editor workflow. unlimitedcodex is an independent OpenAI-compatible API access package that may fit compatible agent or SDK paths.
What should Windsurf users test first?
Test custom base URL support, model IDs, chat/completions behavior, streaming if used, retry behavior, and the 4 concurrent connection cap.
