Guide to the xAI Grok API — Elon Musk's AI model with real-time X/Twitter data access. Covers Grok-2 and Grok-3 models, function calling, vision, long context, and unique features like X search integration and real-time knowledge cutoff.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# xAI Grok API Guide
Grok is xAI's frontier AI model with native X (Twitter) data access. This guide covers API usage, models, and integration patterns.
## Why Grok?
| Feature | Grok Advantage |
|---------|---------------|
| **Real-time X data** | Access to live tweets, trending topics |
| **No knowledge cutoff** | Trained on latest data continuously |
| **Humor/personality** | More engaging conversational style |
| **Function calling** | Full tool support |
| **Vision** | Image understanding |
| **Long context** | 128K+ context window |
## Models
| Model | Context | Best For | Price (1M tokens) |
|-------|---------|---------|------------------|
| **Grok-3** | 128K | Complex reasoning, analysis | $5 / $15 |
| **Grok-2** | 128K | General tasks, faster | $2 / $10 |
| **Grok-2-mini** | 128K | Quick responses, budget | $0.50 / $2 |
## Quick Start

How to install
mdr add nirholas/three.ws/xai-grok-api-guide@sha256:8822aa4211730e92The line at the top of this page pins the label git:20260501.87cefc9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
