Overview
What Gemini API is
The API supports text and multimodal generation, image and media workflows, structured output, function calling, tools, agents, streaming, and background execution. Google AI Studio provides a browser environment for prompts, keys, prototypes, and usage monitoring.
Google offers free, paid, and enterprise access paths, but model availability, quotas, data-use terms, and token prices differ. Production teams should select a specific model and endpoint, secure API keys, and test cost and safety behavior on real workloads.
Use cases
Who Gemini API is best for
The strongest fit depends on the job you need the product to complete, not the size of its feature list.
Google AI Studio prototypes
Teams that want to test prompts and models before exporting code to an application.
Capabilities
Core Gemini API features
Interactions API
Supports stateful, multimodal, multi-turn, and agentic workflows.
Google GenAI SDK

Process
How the Gemini API workflow works
Step 1
Create a key
Use Google AI Studio to create a project and API key or configure an appropriate OAuth flow.
Step 2
Prototype and choose a model
Test prompts and capabilities in AI Studio, then select the endpoint and model.
Step 3
Build and monitor
Use an official SDK or REST, set limits, and review usage, quality, and safety.
