Get started with the Interactions API
Summary
The Interactions API is now generally available and serves as a unified interface for interacting with various Gemini models and agents. It simplifies complex interactions—ranging from synchronous model calls to multi-step agent workflows in remote environments—by providing a single API endpoint. The API supports stateful operations by allowing users to pass the previous interaction ID, enabling iterative refinement of outputs (e.g., image editing) without re-uploading source data.
Key takeaways
-
Unified Model Access
0:10
The Interactions API provides easy access to all Gemini models and agents through a single interface, simplifying development across various Google AI capabilities.
-
Stateful Interactions
4:05
The API is stateful; developers can pass the previous interaction ID to build upon prior results, which is crucial for iterative processes like image editing or complex data processing.
-
Advanced Capabilities
0:18
New features include managed agents, background execution tool improvements, Deep Research, and media generation (e.g., Nano banana for images, Lyriq 3 for music, TTS for speech).

API Architecture & Usage
12s
The API supports both synchronous calls (direct model interaction) and complex asynchronous agent tasks (e.g., multi-step installations in a remote environment).
-
Workflow Demonstration
260s
A photo editing application was built using the Gemini Interactions API skill within an AI IDE (Anti-gravity). The process involved transcribing audio input via an A transcribe API endpoint (using Gemini 3.5 Flash) and then performing iterative image edits with Nano banana, leveraging the previous interaction ID for continuity.

Implementation Details
345s
The setup required configuring environment variables (API key), using NPM to install dependencies, and running a development server (`npm run dev`) to create an API backend in Server JS.
