}'What teams build with it
Literature review agents
Find papers by the method or finding they describe, not just title keywords.
Citation discovery
Follow citation counts and references to the work a field builds on.
Research RAG
Ground answers in abstracts and full paper text instead of summaries.
Searchable alongside the general web index
Research papers live in the same index as the open web. None of these sources requires a separate API or integration: use the same /search endpoint and API key you already use.
Query research papers on their own, or mix them with web results in a single call.
