Grok AI API: Developer Guide to xAI's API, Pricing, SDK, and Console

xAI offers an API for Grok, letting developers integrate Grok's language models into their own applications. It's similar in concept to the OpenAI API — you send prompts, you get responses, you pay per token. Here's what you need to know to get started.

Getting Access to the Grok API

Go to x.ai/api (xAI's developer portal) and sign up for API access. You'll need to create an xAI account if you don't have one. Once approved, you get an API key from the developer console.
API access is separate from consumer Grok subscriptions. Having a SuperGrok subscription doesn't give you API access, and vice versa. They're different products for different use cases.
As of mid-2026, xAI's API is generally available — no waitlist. You can start making requests immediately after getting your key.

Grok API Pricing

xAI charges per token, with separate rates for input tokens (your prompts) and output tokens (Grok's responses). Pricing is competitive with OpenAI and Anthropic at comparable model tiers. Exact rates vary by model version and are published on xAI's pricing page.

The API uses a prepaid credit system. You load credits into your account, and usage deducts from your balance. There's no monthly subscription for API access — it's pure pay-as-you-go.

For high-volume use, xAI offers committed-use discounts. Contact their sales team for enterprise pricing.

Available Models via API

The API gives access to Grok's models at different performance tiers. Grok 3 is the standard model — good balance of capability and cost. Grok 3 with Super reasoning mode is available at a higher per-token rate for complex tasks.

Model availability may differ slightly from what's available in the consumer Grok chat interface. Check the API documentation for the current model list.

Grok SDK and Integration

xAI provides an official Python SDK for the Grok API. Install it with pip:


pip install xai-sdk

The SDK handles authentication, request formatting, streaming responses, and error handling. For other languages, you call the REST API directly using standard HTTP clients.

Key SDK features: chat completions (standard and streaming), image generation via Aurora API, function calling for tool use, and embeddings for semantic search.

The Grok Console (console.x.ai) is the web-based developer dashboard. You can manage API keys, monitor usage, view billing, and test prompts directly in the browser.

Grok API vs OpenAI API

Both serve the same purpose: programmatic access to AI models. The choice depends on which model works better for your use case and price point.

Grok's API advantage is real-time X data access — if your application needs to process or analyze social media conversations, no other API offers native access to X's data stream. For standard text generation, coding, and analysis, OpenAI's API is more mature with better documentation and a larger developer community.

For most developers, the practical answer is: use whichever model produces better results for your specific task. Both have free credits for testing, so try both before committing.
