Cursor setup

What you configure

The Cursor path is intentionally simple: provide the endpoint, the key, and a supported model slug. The full guide covers where those fields sit in the UI.

API key

Your CorvusLLM key authenticates requests and connects usage to prepaid balance.

Custom base URL

The base URL lets Cursor send OpenAI-compatible requests through CorvusLLM instead of a direct provider account.

Model choice

Pick a supported coding model from the current catalog and test one small prompt before larger repo work.

Use cases

For IDE and coding workflows

Cursor users usually care about coding quality, model availability, and cost control. CorvusLLM keeps those decisions visible instead of hiding behind a vague package.

Use this page when

  • You are checking whether Cursor can use a prepaid CorvusLLM API key.
  • You need to understand custom base URL, model slug, and billing requirements before setup.
  • You want the commercial overview before following the technical Cursor guide.
  • You need data-handling and not-affiliated disclosures before using a repo context.
Pricing and access

Prepaid balance for coding sessions

Start small, test your Cursor workflow, then top up if the model mix and latency fit your use case.

What you get

A CorvusLLM key, proxy base URL, and access to supported model families shown by the live catalog.

How pricing works

Usage is deducted from prepaid balance. The pricing tracker explains comparison logic and official-rate references.

Refund and replacement policy

If confirmed payment does not unlock access after a short processing delay, support can trace the order with proof.

Data handling warning

Do not send sensitive or regulated data through shared API proxies. Cursor can expose repository context in prompts, so review your workspace and secrets before using any third-party API route.
