One API key for Claude, GPT, Gemini, Grok, DeepSeek, FLUX and Veo

A developer built LazySusan, an API and zero-dependency Python SDK that routes chat, image and video models from providers including Anthropic, OpenAI, Google, xAI, DeepSeek, FLUX and Veo through a single API key and prepaid balance. Switching between models requires changing only a model string, and responses return usage cost in credits. The SDK is typed, supports Python 3.9+, and installs via pip.
