xAI Grok API

Integrate xAI's flagship Grok models, including Grok-4, into your applications via a robust, developer-focused API for high-performance, truth-seeking AI capabilities.

The xAI Grok API is your programmatic gateway to Grok’s powerful LLM family, designed for developers building intelligent applications. Access models like Grok-4, which features a massive 256,000-token context window and an advanced reasoning engine. The API supports critical functions: real-time streaming, structured JSON output, and function calling for tool integration. Setup is fast: create an xAI account, generate your API key, and begin development using the native Python SDK or the OpenAI-compatible REST endpoints (e.g., `https://api.x.ai/v1/chat/completions`).
