Preparation

Field	Value
Provider	OpenAI Compatible
Base URL	https://www.potatoai.cc/v1
API Key	The API key created in the PotatoAI.cc console
Model	The complete model ID shown in the console

Configuration Steps

1. Open Model Settings

Open Cursor Settings, then find the Models, API Keys, or custom model provider area. Menu names may vary slightly between Cursor versions.

2. Add a Compatible Service

Choose OpenAI Compatible. If your Cursor version only exposes OpenAI settings, use the entry that allows you to override the Base URL.

3. Fill In the Endpoint and Key

Set the Base URL to https://www.potatoai.cc/v1, then paste the API key created in the PotatoAI.cc console.

4. Add the Model

Copy the complete model ID from the console. Do not remove version numbers, hyphens, capitalization, or other symbols.

Model ID Must Match

Cursor will fail to call the model if the ID does not exactly match the model shown in the PotatoAI.cc console.

5. Enable and Test

Save and enable the model, then send a short request in Chat or Agent to confirm that the model returns normally.

Accounts, Built-In Models, and Switching

Topic	Note
Cursor account	You do not need to sign out. Cursor login handles editor sync and built-in Cursor features; the PotatoAI.cc API key only handles the configured model requests.
Built-in features	Not every Cursor feature goes through PotatoAI.cc. Features such as Tab Completion may still use Cursor's built-in services.
Switching back	If global Override OpenAI Base URL is enabled, turn it off before using official Cursor/OpenAI models. Enable it again when switching back to PotatoAI.cc.
Free plan limits	Cursor may limit custom API keys, Agent, or Edit features based on your current plan. Follow the Cursor client prompt.

FAQ

Symptom	Fix
No Verify button	Some newer versions take effect after saving. Select the added model, send a short message, and check PotatoAI.cc usage logs.
model not found	Copy the full model ID again from the console and confirm the current account group has permission for that model.
Official models also fail	Turn off Override OpenAI Base URL and retry. In some versions, this setting affects other OpenAI models.
Network error / TLS error	Confirm the address is https://www.potatoai.cc/v1, then set HTTP Compatibility Mode to HTTP/1.1 in Network settings and test again.
Tab still does not use PotatoAI.cc	This is Cursor product behavior. Custom API keys mainly apply to supported chat models; Tab Completion may continue using built-in models.

Recommendation

Dedicated Key

Create a separate API key for Cursor. This makes it easier to review usage by client, rotate the key, or disable Cursor access independently.
