- **Perform research tasks**: Automate multi-step research workflows to gather, synthesize, and summarize information

In Sim, the Exa integration allows your agents to search the web for information, retrieve content from specific URLs, find similar resources, answer questions with citations, and conduct research tasks—all programmatically through API calls. This enables your agents to access real-time information from the internet, enhancing their ability to provide accurate, current, and relevant responses. The integration is particularly valuable for research tasks, information gathering, content discovery, and answering questions that require up-to-date information from across the web.
