How do I get free API credits for Grok?

You can receive $150/month in free credits by going to the xAI Console, navigating to Settings, and enabling the data sharing opt-in.

What should I do if I get a 'rate_limit_exceeded' error?

You should implement exponential backoff in your code to retry requests and monitor your Requests Per Minute (RPM) to ensure they stay within the limits of your specific model tier.

What is the recommended way to store my xAI API key?

It is recommended to use environment variables (e.g., XAI_API_KEY) or a .env file that is excluded from your git repository via .gitignore to prevent accidental exposure.

Is the xAI API compatible with the OpenAI SDK?

Yes, the xAI API is fully compatible with the OpenAI SDK; you simply need to update the base URL to https://api.x.ai/v1 and provide your xAI API key.
