How much does using Grok on SpaceXAI cost, and how can I access it?

Updated

SpaceXAI (x.ai) does not publish a single flat price for Grok on the pages shown here. Instead, the site routes cost questions to a dedicated Pricing page and offers a "Try for free" entry point, so the practical answer is: check x.ai/pricing for current rates, and start with the free trial if you want to test before committing. Access itself is available through several channels — a unified API, iOS and Android apps, Grok on X, and a Grok Bot — with separate tracks for business, government, and developers.

Where to find actual pricing

The site's navigation includes a Pricing link (x.ai/pricing), which is the only place cost details are surfaced in the available material. No specific dollar figures, token rates, or subscription tiers appear on the homepage, so any number you see elsewhere should be verified against that page.

What the homepage does confirm:

  • A "Try for free" button exists, indicating you can evaluate Grok at no stated cost before paying.
  • A "Get API Access" and "Get API Key" flow exists for developers, but the page does not state whether API usage is billed, metered, or included in a plan.

Because pricing is not described in the source material, treat "free" as applying to the trial entry point only — not as a claim that the API or full product is free.

Ways to access Grok

The site lists several distinct access paths, aimed at different users:

Access method Who it's for How to start
Grok API Developers building apps Get API Key, then read the docs
iOS / Android apps General users on mobile Download from the app stores
Grok on X Users already on X Access via the X platform
Grok Bot Chat-style use Open the Bot entry point
Business / Government Organizations Contact Sales

For organizations, the Contact Sales route is the stated path — pricing and terms for business or government use are handled through that conversation rather than a public rate card.

What the API gives you

If you're evaluating cost against capability, the API is described as "One API. Every modality" — text, code, voice, images, and video through a single unified interface. The site advertises:

  • 1M+ API calls per day
  • <200ms median latency
  • 5+ model families

The current model named on the page is Grok 4.7. The API is OpenAI-compatible, so you can point an existing OpenAI client at https://api.x.ai/v1 with your XAI_API_KEY, or use the xai_sdk Python package or the @ai-sdk/xai TypeScript package.

A minimal call looks like this:

curl https://api.x.ai/v1/chat/completions \
  -H "Authorization: Bearer $XAI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "grok-4.7",
    "messages": [{"role": "user", "content": "Explain quantum computing"}]
  }'

The expected result is a standard chat completion response with the model's answer in choices[0].message.content.

How to decide

  • Just want to try it: use the "Try for free" entry point, or download the iOS/Android app.
  • Building an integration: get an API key, confirm rates on x.ai/pricing, then test with the OpenAI-compatible endpoint or the SDK.
  • Buying for a team or agency: go through Contact Sales, since business and government access is handled separately.

The one thing to do before any paid commitment is open x.ai/pricing directly — it's the only authoritative source for current Grok costs, and the homepage deliberately doesn't quote numbers.
