Free Grok API key on sign-up
Free Grok API key on sign-up through GrokAPI, the fast way to get production access without a VPN, subscription, or waitlist. Below: what you get, how to plug it in, and how it compares to going direct.
Start with free test credit
New accounts receive test credit after registration. Generate a key in the dashboard and use the credit to test Grok 4.5, verify connectivity, and estimate token consumption before adding funds. The credit is a balance, not a separate limited API key.
What GrokAPI provides
An OpenAI-compatible endpoint for Grok 4.5, usage-based billing, USDT payments, integration guides, and support through Telegram.
Get started in five minutes
Register with email or Google, copy your API key, point base_url at our endpoint, and send your first chat completion. No card required for the free credit.
Gateway or direct API
A gateway adds its own billing, endpoint, and support layer while preserving a familiar API format. Review Grok 4.5 availability, pricing, data handling terms, and rate limits before choosing it for production. GrokAPI is independent from xAI.
Free credit is added instantly after sign-up.
