Gemini API

Gemini API is Google's developer platform for building applications with Gemini models. It gives developers API access to multimodal models that can work with text, code, images, audio, video, and structured workflows, making it useful for AI agents, chatbots, coding tools, document analysis, research systems, and product features. For founders and SaaS builders, Gemini API is relevant because it combines strong model access with Google's developer tooling. Teams can prototype in Google AI Studio, create API keys, integrate Gemini into applications, and choose models based on speed, cost, and capability. The official pricing page lists free-tier and paid pricing options for Gemini models, with costs varying by model and token usage. This makes Gemini API suitable for both early experimentation and production features that require scalable multimodal AI. For FutureStack, Gemini API belongs in Developer Tools because it is one of the major model APIs builders compare against OpenAI API, Claude API, Mistral, Cohere, and OpenRouter. It is best for developers and founders building AI apps, agents, assistants, analysis tools, and multimodal product experiences.
