Building web search-enabled agents with Strands and Exa
Summary
The Strands Agents SDK, an open-source framework from AWS, now integrates with Exa, an AI-native web search engine, to enhance AI agents with real-time, structured web information. This integration addresses the limitations of general-purpose search APIs by providing clean, LLM-consumable content without requiring extensive post-processing. The Strands Agents SDK uses a model-driven architecture where the LLM autonomously decides when and how to use tools. The Exa integration exposes two core tools: `exa_search` for semantic web search with category and filter support (e.g., news, research papers, GitHub) and `exa_get_contents` for retrieving full-page content from specified URLs, including live crawling for freshness. This enables agents to perform multi-step tasks like deep research, fact-checking, and competitive intelligence by incorporating current web knowledge directly into their reasoning loops.
Key takeaway
For AI Engineers building web search-enabled agents for research or competitive intelligence, integrating Strands Agents SDK with Exa simplifies access to structured, real-time web data. You should leverage the `exa_search` and `exa_get_contents` tools to enable your agents to autonomously perform multi-step information gathering, reducing hallucination and improving token efficiency by working with distilled, relevant content.
Key insights
Integrating AI-native search engines with agent SDKs provides structured, real-time web data for LLM-driven workflows.
Principles
- Model-driven agents autonomously select and use tools.
- Semantic search improves relevance over keyword matching.
- Structured content reduces LLM post-processing overhead.
Method
The Strands Agents SDK uses an agent loop where an LLM, guided by a system prompt, calls `exa_search` and `exa_get_contents` tools to iteratively gather and synthesize web information for multi-step tasks.
In practice
- Use `exa_search` with category filters for targeted content.
- Control token usage by setting `maxCharacters` on content.
- Employ `deep` search mode for comprehensive research tasks.
