You create one API key. You use it for everything. Cursor. Open WebUI. Local scripts. Prototype apps.

It seems easy at first. Then your costs spike. You do not know why.

One key removes visibility. You face these risks:

• A script stuck in a loop.
• A teammate testing a large model.
• A leaked key in your code.

All these look like the same user. This is bad for your budget.

Create one API key per tool.

• cursor-dev
• production-backend
• local-test

This is basic cost isolation.

Debugging gets faster. You identify errors by the key. You see if the problem is only in Cursor.

Leaks also hurt less. You disable one tool key. You limit the damage. You keep your main service running.

Use these rules:

• Give keys clear names.
• One key per AI client.
• One key per environment.
• Set low limits for tests.
• Set high limits for production.
• Check logs before you raise limits.
• Delete unused keys.

Forget the model for a moment. Ask which tool spends your money. Ask if you are able to stop it fast.

If you do not know the answer, your setup is too loose. Split your keys now.
