The company research API for AI agents
Query companies programmatically and receive structured, sourced answers that your own agents or applications can consume.
Match against a maintained business index or search the open web when the company you want is not in any list.
Define a brief with sector, size, location, and capability filters, and get back candidates rated for fit.
Every answer includes its origin, so findings can be verified and audited rather than accepted blindly.
A free, AI-powered academic search engine for 240M+ papers across every scientific field
Search 241 million-plus publications from every scientific field using natural-language queries that match meaning rather than exact keywords.
Each indexed paper gets a one-sentence machine-generated TLDR so you can triage results before committing to reading the full text.
An augmented PDF reader that highlights citations, definitions, equations and figures inline, and shows which later papers cited the passage you are reading.
See how a paper was cited, whether citations were influential, and which references shaped the work — useful for literature reviews and citation chasing.
