Google Search (via ADK grounding)

Google Search (via ADK grounding) connects AI agents to real-time web data to eliminate hallucinations and provide cited, up-to-date answers.

Google Search grounding within the Agent Development Kit (ADK) gives Gemini-powered agents a direct line to the live web. By integrating the google_search tool, agents move beyond static training data to retrieve 2026 news, stock prices, and technical documentation on demand. The system handles the heavy lifting: it analyzes user intent, executes precise search queries, and injects relevant snippets into the model context. Every response includes groundingMetadata with source URLs and confidence scores (0.0 to 1.0), ensuring that facts are verifiable and transparent for production-grade applications.
