What is an API Key?

An API Key is your authentication credential for accessing Model Router. It’s like a password that allows you to make requests to the API. Each API key is associated with a specific group that controls which models you can access and how much quota you have.

​
How to Create an API Key

​
Step 1: Navigate to API Key Management

  1. Log in to the Memorylake Console
  2. Click on “API Keys” or navigate to the API Keys management page

​
Step 2: Create a New API Key

  1. Click the “Create API Key” button
  2. Enter a name for your API key (this is just for your reference)
  3. Configure the settings:
    • Name: Choose any name you like (e.g., “My Project API Key”)
    • Quota: Set to unlimited if you want no restrictions, or set a specific limit
    • Group: Select the API key group (this determines which models are available)
The API key name is only for your reference and can be changed later. The quota setting controls how much you can use before needing to recharge.

Step 3: Save Your API Key

After creating the API key, you’ll see a key that starts with sk-. Important: Copy and save this key immediately, as you won’t be able to see it again after closing the dialog.
Make sure to save your API key in a secure place. If you lose it, you’ll need to create a new one. Never share your API key publicly or commit it to version control.
