Grok Imagine API: How to Generate Images with xAI Grok via One API Key#

Grok Imagine is xAI's image generation capability built into the Grok model family. Developers searching for Grok Imagine access usually want to know one thing: can I call it through an API, and how?

The short answer: yes. Through Crazyrouter, you can access Grok image generation using a single API key, with OpenAI-compatible request formats. The same key also gives you access to GPT Image, Midjourney, Flux, DALL-E, and other image models — no separate integrations needed.

What Is Grok Imagine?#

Grok Imagine is xAI's image generation feature, available through the Grok model ecosystem. Key capabilities:

• Text-to-image generation — describe what you want, get an image
• Multiple styles — photorealistic, artistic, illustration, and more
• Fast generation — typically under 10 seconds per image
• Integrated with Grok chat — can be triggered within conversational workflows

Unlike standalone image generators, Grok Imagine is part of a broader AI model family that includes chat, reasoning, and code generation.

How to Access Grok Imagine via API#

Crazyrouter provides unified access to Grok models through standard API endpoints. Here's how to get started.
