Paying for the Grok API with crypto
Updated:
Top up your Grok API Dev balance with crypto and use it for Grok model requests. USDT, USDC, ETH, BTC are supported, with no bank card required.
Why you might need to pay in crypto
xAI applies geographic restrictions that prevent billing and access to Grok models in blocked regions, making crypto one possible alternative. Grok API Dev offers crypto top-ups through a separate gateway, so a bank card is not required.
Payment through a third-party gateway
xAI does not accept crypto directly. Grok API Dev acts as a gateway: top up with crypto and access the same models through an OpenAI-compatible API.
Pay for Grok with USDT, USDC, ETH, BTC
Choose the cryptocurrency that suits you, top up your balance, and pay only for the tokens you use. There is no subscription or required monthly payment.
How to top up
Create an account
Registration takes under a minute and adds $0.25 in test credit, so you can check the connection before paying for anything.
Open the balance section
The dashboard lists the currencies and networks that are currently supported, along with the address to send to. The list lives there rather than here because it changes.
Pick the currency and network
Choose the pair you actually hold. The network matters as much as the currency — the same token on a different chain is a different address.
Send the exact amount
Transfer to the address shown and wait for network confirmations. The balance is credited once the transaction is confirmed, and the amount appears in your account history.
Why a gateway is simpler than a direct account
A gateway sits between your code and the upstream model provider. You hold one balance and one Grok API Dev key, and send OpenAI-compatible requests to the Grok API Dev base URL. The gateway handles upstream billing and routing.
What else comes with it
Rates 50% below official
Published Grok model token rates are half of xAI's public rates as of the verification date. The Grok API Dev base URL is different.
Test credit before you pay
A new account gets credit on sign-up, enough to confirm the key and base URL work before any top-up.
Drops into existing code
The endpoint is OpenAI-compatible: change the base URL, the key, and the model name, and keep the rest of your integration.
More than Grok on one platform
The same account and API key give you access to other top models. Everything runs on one platform, with no separate integration for each provider.
Frequently asked questions
Which currencies and networks are supported?
You can top up with USDT, USDC, ETH, BTC. The dashboard shows the current list of currencies and available networks. Check it before sending a transfer.
Is there a minimum top-up?
Yes. The minimum amount appears in the top-up section after you choose a currency and network. Check it before each transfer.
How can I pay for the Grok API with crypto?
Use the third-party Grok API Dev gateway. Create an account, open the top-up section, choose a cryptocurrency and network, then send the specified amount to the displayed address.
Do I need a VPN to pay or to use the API?
A VPN is not a product requirement. Use the sign-up test credit to verify access from your own network before topping up; availability can vary by network and applicable local rules.
