Frequently asked questions
Is the Grok 4.3 API on 97AI.PRO the same as the official xAI API?+
Yes — same underlying model, same outputs. 97AI.PRO resells wholesale capacity so pricing is 58% lower and payment is available globally including in regions where xAI doesn't ship directly.
Do I need a xAI account?+
No. One 97AI.PRO account and API key gives you access to Grok 4.3 and 150+ other models across providers.
What SDKs are supported?+
Any HTTP client works. For chat endpoints, the OpenAI SDK works out of the box by pointing `base_url` to `https://97ai.97claude.com/api`.
How do I test before going to production?+
Sign up, add $5 in credits, and hit the endpoint from your terminal. There's no long-form onboarding or contract.
What if a generation fails?+
You pay $0. The API returns `state: "FAILURE"` with an error object; credits are refunded automatically. This is the "zero-risk billing" policy.
