No. One 97AI.PRO account and API key gives you access to Claude Opus 4.6 plus 173 other models across providers.
What SDKs are supported?+
For chat endpoints, the OpenAI SDK works out of the box by pointing `base_url` to `https://www.lithovas.com/api`. Any HTTP client also works.
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.
