Inquiry regarding official API or commercial license for using Cursor's engine as a backend component

Hi everyone,

I am currently developing a professional software platform and I am looking for ways to integrate specific code-analysis and refactoring capabilities into one of my application’s features.

I am very impressed with how Cursor’s engine handles code context, multi-file intelligence, and complex reasoning tasks. I would like to explore the possibility of using Cursor’s engine programmatically as a specific module within my platform.

Is there an official public API, SDK, or a commercial/enterprise licensing tier that allows developers to programmatically leverage Cursor’s engine (or CLI capabilities) on a backend server to power a specific feature of a larger application?

If not, what is the official stance on using Cursor CLI in a headless environment for programmatic tasks, specifically when it is restricted to just one modular feature of a larger application?

Thanks!

Hey, thanks for the request. Yep, there’s an official way to do this, no private or undocumented API needed.

On licensing and ToS, a teammate already answered an almost identical request in this thread: API / SDK - Terms of use - Question

Quick summary, quoting their answer: using Cursor as a backend AI service inside your product is a supported and intended use of the Cursor SDK. Main limits:

  • you can’t resell Cursor itself as a standalone service, meaning you can’t give third parties access to Cursor or usage under your account
  • you can’t use Cursor outputs to train a competing model
  • regulated data like HIPAA, PCI, etc needs a separate agreement

Billing is usage based under the plan and limits of the account tied to the API key. There’s no separate engine license SKU. You’re on the Free tier right now, so for production you’ll need a paid plan and an API key. For commercial or enterprise details, it’s best to reach out to sales via [email protected].

Let me know if you want me to expand on any part of this.
