Gemini API

Gemini API is Google’s unified interface for accessing Gemini family multimodal models that can understand and generate text, code, and images, and reason over mixed inputs like text plus images. It is designed for application developers to integrate advanced language and vision capabilities into products via a single, consistent API surface.
