Integration
Use Cursor with your unlimitedcodex API key.
After manual setup delivery, configure Cursor to call the delivered OpenAI-compatible base URL instead of the default OpenAI endpoint.
- OpenAI-compatible /v1 base URL swap
- Exact package-specific model IDs from your setup email and authenticated GET /v1/models
- Unlimited token consumption with 4 concurrent connections
- 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
Quick answer
Set up Cursor 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
Cursor + unlimitedcodex OpenAI-Compatible API combines 4 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 Cursor, then run one tiny chat/completions request and any supported image or embedding checks before long runs.
Decision summary
Best fit
Cursor 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 Cursor before one small request.
Setup steps
Step 1
Complete checkout and wait for delivery
On /pricing, 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. Delivery takes 10 minutes to 5 hours.
Step 2
Open Cursor settings
In Cursor, open Settings and find the OpenAI-compatible or custom API configuration section for your account.
Step 3
Paste base URL and API key
Set the delivered unlimitedcodex /v1 base URL and API key, then copy the exact model ID from the setup email and authenticated GET /v1/models.
Step 4
Test a coding request
Run a small refactor or test generation task, then review request logs and 4-connection usage signals in the dashboard.
Example configuration
