## About xAI API

The xAI API gives developers access to xAI's Grok models for text, reasoning, vision and image generation, with features such as function calling and live search.

xAI was founded by Elon Musk in 2023 and develops Grok, which is also available in the X app. The API is billed by usage. Developers can use it to add Grok's conversational, reasoning and real-time search abilities to their own products, and the API follows a format similar to other popular AI APIs, which makes switching or comparing providers easier.
