Valyu
Freemium
Valyu provides search, content extraction, answer, and DeepResearch APIs for AI agents and knowledge-work applications. It combines open-web results with financial, scientific, biomedical, legal, economic, and other specialist sources, returning cited content and research outputs.
Valyuとは？
Valyu is an API platform for AI-powered search and research. Its Search API lets agents query the open web alongside specialist and licensed sources such as academic papers, SEC filings, market data, clinical trials, patents, and economic indicators. Results can include ranked URLs, full-text excerpts, content, source metadata, and relevance scores.
The platform also provides Contents, Answer, and DeepResearch APIs. Contents extracts clean material from URLs, while Answer combines search with AI synthesis. DeepResearch performs multi-step investigation and returns a cited report, with research depth configurable for workflows that may run from several minutes to several hours. Valyu is positioned for AI products, research workflows, and research desks that need traceable information rather than a standalone web-search box.
