Complete Setup Guide
Get Your Moonshot AI API Key
First, you'll need to obtain an API key from Moonshot AI. This key allows you to access their AI models directly and pay only for what you use.
- Visit Moonshot AI's API console
- Sign up or log in to your account
- Navigate to the API keys section
- Generate a new API key (copy it immediately as some providers only show it once)
- Save your API key in a secure password manager or encrypted note
Sometimes, this provider will require you to add a payment method to your account before you can use your API key to chat with AI. So, to avoid any hiccups, make sure you've got a payment method set up and ready to go!
Important: Keep your API key secure and never share it publicly. Store it safely as you'll need it to connect with TypingMind.
