What is Cursor?
Cursor is an AI-powered code editor built on top of VS Code. It adds AI features directly into your editing workflow: tab completions that predict your next edit, a chat panel that can read and modify your codebase, and inline generation that writes code from natural language descriptions.
What makes Cursor different from just using ChatGPT alongside your editor is context. Cursor sends your open files, recent edits, and project structure to the model so it understands what you're working on. That context is also what makes data residency matter: your proprietary code is being sent to an LLM. With EUrouter, those requests go through European servers instead of US ones.
Quick to integrate
A few lines of code is all it takes. Swap your base URL and you are routed through EUrouter.

Follow these steps to connect your application to EUrouter.
Open Cursor settings
In Cursor, go to Settings and find the "Models" section. Select "OpenAI API Key" to configure a custom endpoint.
Set your API key and base URL
Enter your EUrouter API key and set the base URL to https://api.eurouter.ai/v1.
Choose your model
Select any model available through EUrouter (GPT-4o, Claude, Mistral, etc.) and start coding with EU-hosted AI.
Why use Cursor with EUrouter
Code completions through Europe
Cursor sends your surrounding code as context with every completion request. That's your proprietary code leaving your machine. With EUrouter, those requests route through EU servers, so your codebase never touches US infrastructure.
- Tab completions and inline suggestions go through EUrouter's EU servers
- Code context (open files, recent edits) stays within European jurisdiction
- EUrouter's EU endpoints are optimized for low latency, so suggestions still feel fast
- Works with all Cursor AI features: completions, chat, inline edits, and code generation
Chat with any model
Cursor's chat panel is where developers ask questions about their code, debug errors, and generate new functions. Through EUrouter, you can use any model for this: GPT-4o, Claude, Mistral, whatever works best for your workflow. One API key, no switching between accounts.
- Access all models available through EUrouter from Cursor's chat panel
- One API key covers every model, no separate accounts needed
- Switch models on the fly depending on the task
- Unified billing so you see exactly what each developer spends
Enterprise-friendly AI coding
For development teams at companies subject to EU data regulations, Cursor with EUrouter is a practical setup. Each developer gets their own API key with a spend limit. The company gets a centralized dashboard showing usage across the team. No proprietary code leaves Europe.
- Issue per-developer API keys with monthly spend caps
- All code interactions (completions, chat, edits) stay GDPR-compliant
- Centralized usage monitoring shows who's using what and how much it costs
- Useful for regulated industries (finance, healthcare, legal) where code data residency matters
