OpenAlex Search

This tool uses Perplexity AI Sonar to perform comprehensive web searches with synthesized, researched answers. Unlike simple search engines, Perplexity provides cited sources and contextual understanding. Best for research questions, current events, fact-checking, and queries requiring authoritative sources. Responses include citations and contextual analysis.

This tool searches the Internet Archive OpenLibrary database for books, authors, and works. Returns comprehensive book metadata including title, author, publication year, ISBN, edition count, and availability information. Best for finding books by title, author, or subject. OpenLibrary contains millions of books from libraries around the world.

This tool delegates research and search tasks to a specialized subagent with access to multiple search tools (OpenAlex, OpenLibrary, Web Search, Perplexity). Useful for complex research queries that benefit from using multiple search sources or when you want a specialized research assistant to handle the search comprehensively. The subagent can orchestrate multiple tool calls and synthesize findings across academic, web, and book searches.
