About SpaceXAI (Grok)

Grok is SpaceXAI's flagship family of large language models designed to deliver truthful and insightful AI responses. The SpaceXAI API provides developers with access to powerful models including Grok-4 and Grok-2-1212 (with a 131K token context window), supporting multimodal capabilities like vision processing and image generation via Flux.1. Key features include function calling for API automation, compatibility with OpenAI/Anthropic SDKs, structured outputs, and enterprise-grade security with GDPR/HIPAA compliance. The platform offers Python and JavaScript SDKs for easy integration into applications ranging from conversational AI to complex workflow automation.

Step by step guide to use SpaceXAI API Key to chat with AI

1. Get Your SpaceXAI API Key

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

  1. Visit SpaceXAI'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
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.

2. Connect Your SpaceXAI API Key on TypingMind

Once you have your SpaceXAI API key, connecting it to TypingMind to chat with AI is straightforward:

  1. Open TypingMind in your browser
  2. Click the "Settings" icon (gear symbol)
  3. Navigate to "Models" section
  4. Click "Add Custom Model"
  5. Fill in the model information:
    Name: grok-4-0709 via SpaceXAI (or your preferred name)
    Endpoint: https://api.x.ai/v1/chat/completions
    Model ID: grok-4-0709 for example (check SpaceXAI model list)
    Context Length: Enter the model's context window (e.g., 32000 for grok-4-0709)
    SpaceXAI Endpoint URL input fieldgrok-4-0709https://api.x.ai/v1/chat/completionsgrok-4-0709 via SpaceXAIhttps://www.typingmind.com/model-logo.webp32000
  6. Add custom headers by clicking "Add Custom Headers" in the Advanced Settings section:
    Authorization: Bearer <GROK_API_KEY>:
    X-Title: typingmind.com
    HTTP-Referer: https://www.typingmind.com
  7. Enable "Support Plugins (via OpenAI Functions)" if the model supports the "functions" or "tool_calls" parameter, or enable "Support OpenAI Vision" if the model supports vision.
  8. Click "Test" to verify the configuration
  9. If you see "Nice, the endpoint is working!", click "Add Model"

3. Start Chatting with SpaceXAI models

Now you can start chatting with SpaceXAI (Grok) models through TypingMind:

  • Select your preferred SpaceXAI model from the model dropdown menu
  • Start typing your message in the chat input
  • Enjoy faster responses and better features than the official interface
  • Switch between different AI models as needed
