Open-Source AI Research Engine Taps 100+ Hidden Data APIs

Current AI research tools rely heavily on web search, achieving only 40-80% citation accuracy. This open-source research engine catalogs 100+ free APIs and databases that Google doesn't index—including academic papers, patent filings, package registries, and market data. Developers can now use a Claude Code skill to run multi-agent workflows that access specialized data sources, making AI research more comprehensive and reliable.
