Get Your DeepInfra API Key

First, you'll need to obtain an API key from DeepInfra. This key allows you to access their AI models directly and pay only for what you use.

  1. Visit DeepInfra's API console
  2. Sign up or log in to your account
  3. Navigate to the API keys section
  4. Generate a new API key (copy it immediately as some providers only show it once)
  5. Save your API key in a secure password manager or encrypted note

⚠️ Important: Keep your API key secure and never share it publicly. Store it safely as you'll need it to connect with TypingMind.
