Is there a free Grok API?
Updated:
Short answer: Grok API Dev has no permanent free tier. It provides a small sign-up test credit, then charges published per-token rates that are currently half of xAI's public rate.
Why we do not offer a free Grok API
Every model request uses compute resources, so ongoing access is paid. Grok API Dev currently publishes rates 50% below xAI's public rate, plus a small test credit and pay-as-you-go billing with no subscription or monthly minimum.
What Grok API Dev gives you instead
Grok API Dev has three practical advantages: pricing 50% below the official rate, access to other top models through one API, and crypto payments with no subscription.
50% below the official rate
Published Grok model input and output token rates are half of xAI's public rates as of the verification date. Actual cost depends on token usage and request type.
Other top models on one balance
The same account and API key give you access to other top models. One platform for everything, with no separate integrations.
Crypto top-up, no card
The balance is funded with supported cryptocurrencies. There is no subscription or required monthly payment; current options are listed in the dashboard.
Plus a bonus on top: the test credit
A new account gets $0.25 in credit immediately. That is enough to check your setup and send a few requests before paying. It is a test credit, not a plan for ongoing use.
- Input tokens it covers
- ≈ 250,000
- Or output tokens
- ≈ 83,333
- Enough for
- a few dozen test requests
Treat it as a smoke test: send a few requests, confirm the key and base URL are right, watch the usage counter move. Then decide whether to top up.

Does xAI have a free tier for the Grok API?
There is no permanent free tier for API access. xAI occasionally offers promotional credits, but their terms and availability change. Ongoing use of the Grok API is paid.
Will $0.25 of test credit be enough for me?
It depends on what you mean by enough. For checking that the key and base URL work — comfortably. For a production workload — no: $0.25 covers roughly 250,000 input tokens or 83,000 output ones, which is a few dozen test requests.
What is the cheapest way to use Grok models for real workloads?
The simplest option is to connect through Grok API Dev. Requests to Grok models cost 50% less than xAI's official rate, and you can keep using the familiar OpenAI-compatible request format.
Do I need a card to pay?
No. You can top up your balance with cryptocurrency, so the service remains available in regions where xAI does not accept payments.
