Cursor supports OpenAI-compatible endpoints. After unlimitedcodex manual setup delivery, you can route coding requests through your delivered base URL instead of default OpenAI billing.
Operator-reviewed
Maintained by the unlimitedcodex operator team responsible for manual API setup delivery, base URL handoff, package dates, and customer support workflows.
Before you configure Cursor
Choose GPT-5.5 XHigh Weekly or Monthly, or GPT-5.6 Sol Weekly or Monthly, then wait for delivery of the API key, base URL, setup files, package dates, and exact model ID.
Use only the model ID in the setup email and verify it with /v1/models before running a Cursor task.
Configuration steps
Open Cursor settings and locate the custom OpenAI-compatible API section for your account.
Paste the delivered unlimitedcodex /v1 base URL and API key, then choose the model ID from your setup email.
Run a small refactor or test-generation task, then review request logs and 4-connection usage signals in the dashboard.
Operational guardrails
Plan agent concurrency around the 4 concurrent connection limit. Serialize heavy jobs or queue work if multiple agents run at once.
Use separate keys for development and production environments so you can rotate credentials without disrupting the whole workspace.
