Endigest AI Core Summary
This post explores two integration patterns for using Google's new Interactions API alongside the Agent Development Kit (ADK) and Agent2Agent (A2A) protocol.
•The Interactions API provides a unified endpoint for both raw Gemini models and built-in agents like the Gemini Deep Research Agent.
•Pattern 1 uses the Interactions API as the inference engine for ADK agents, enabling server-side state management via previous_interaction_id and background execution mode.
•Pattern 2 uses InteractionsApiTransport to treat an Interactions API endpoint as a standard remote A2A agent, requiring no changes to existing A2A client code.
•The bridge maps A2A protocol operations (SendMessage, Task, TaskStatus) directly to Interactions API equivalents.
•
Configuration smuggling via A2A extensions allows passing specific settings like thinking_summaries inside AgentCard without breaking the standard protocol.
