What this page answers
Page-specific proof
Codex IDE + 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 Codex IDE, then run one tiny chat/completions request and any supported image or embedding checks before long runs.
Decision summary
Best fit
Codex IDE 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 Codex IDE before one small request.
Setup steps
Step 1
Complete checkout
Pick $19/week or an eligible $59 first month followed by $69/month GPT-5.5 XHigh, or GPT-5.6 Sol at an eligible $69 first week followed by $89/week, or a $179 first month followed by $199/month. Setup usually completes in 10 minutes to 5 hours.
Step 2
Open the delivered setup files
Use the package delivery email for the exact base URL, key, and model IDs. The full key is delivered by email while the dashboard shows safe status and dates.
Step 3
Configure the IDE provider
Set the delivered base URL and key, then select the exact model ID from the setup email and authenticated GET /v1/models.
Step 4
Validate before a long task
Run /models, a chat/completions check, and any image or embedding checks your workflow needs before starting a large repo task.
Example configuration
Provider type: OpenAI-compatible Base URL: <delivered unlimitedcodex /v1 URL> API key: <delivered API key> Model: DELIVERED_MODEL_ID Connection planning: 4 concurrent connections Verification: setup email + authenticated GET /v1/models

FAQ
What do I receive after checkout?
You receive an API key, base URL, setup files, model IDs, activation dates, and package status after manual provisioning.
Can Codex IDE image workflows use this?
If your delivered package supports it, image generation is available through API calls. Always test the image endpoint directly before depending on it.
Why is setup manual?
Manual setup helps ensure the delivered key, base URL, setup files, and dates are provisioned correctly. The expected delivery window is 10 minutes to 5 hours.
