Grok API FAQ
-
Create an AI/ML API account, add credit, then open API keys and choose Create API Key. Pick a Grok model and send your first request. Follow the setup guide.
-
No. You get an AI/ML API key and call Grok through api.aimlapi.com. A key from the xAI Console works only with api.x.ai, and one can't replace the other.
-
No. Grok is the model family from xAI. Groq is a separate company that runs other open models on its own chips, and its keys don't work with Grok. See Grok models.
-
You pay as you go from your AI/ML API balance. Text bills by tokens, images by generation and video by second, and every rate is in the model table. See models and pricing.
-
No. Each Grok request is billed from your AI/ML API balance at the rates in the model table, so you pay only for the tokens, images or seconds you use. Check the rates.
-
For Grok text models, use the OpenAI client in Python or JavaScript with your AI/ML API key and
https://api.aimlapi.com/v1as the base URL. Image and video models use their documented endpoints. See supported SDKs. -
Yes. Grok Imagine Image 2.0 generates and edits images with up to five reference images, and the Grok Imagine video models animate a starting image. Explore Grok Imagine.
-
Store the key in a server-side environment variable. Keep it out of browser code and public repositories, and set permissions and a spending limit in your account. Manage your API keys.
