# Do I need an OpenSea API Key?

An OpenSea API Key is **not required** in order to use NFT Butler. They are provided as part of the service.

However if you want to use your own OS API Keys it's still possible to add your own as described below. There is no benefit other than running on your own OS API Keys when adding them.

### **Using your own OS API Keys**

You can add your own OS API Keys in Settings -> OPENSEA API KEY (legacy)

* You can use your own OpenSea API Key(s) as a strong and **independent** Butler User.
* You add up to 6 OpenSea API Keys to Butler. Each Key will run two token bidding tasks from your own keys.
* Please ensure to only create **1 OS API Key per OS Account** (otherwise your Butler is very likely to run into Rate Limits since multiple API Keys share their Rate Limits from the same Account).
* If you don't have any OS API keys you can still **run Butler from our Backend API Keys**
