Search publication sources
POST /search uses type auto, category publications, and a result count capped at 15. A selected week, month, three-month, six-month, or year window becomes startPublishedDate; the all-time option omits it.

Why Exa
Research discovery needs semantic relevance, recency, and enough context to distinguish a title match from a substantive contribution. Exa searches publication sources and returns focused excerpts for comparison and citation.
The Pipeline
Overview
The demo performs a live Exa search, optionally augments arXiv results with citation counts from OpenAlex, then streams a short synthesis based on the five leading papers.
Steps
Clean paper metadata and enrich citations
The app asks for up to 4,000 characters of relevant highlights per result, cleans titles and abstracts, derives missing arXiv dates, and tries a five-second OpenAlex lookup for citation counts. OpenAlex failure never blocks results.
Summarize the five leading papers with citations
The top five results go to a synthesis model, which defaults to gemini-3.7-flash. The prompt asks for a 250-word summary and citation markers, which are mapped back to the result cards.
Look up a researcher on demand
Selecting a researcher triggers a separate Exa Search for that name plus the word researcher. This call sets category people and numResults 3, and requests the full page text. It leaves type unset, so Exa uses its default.
/search
Endnote
OpenAlex is an optional enrichment layer and is not part of the Exa request. Citation count is therefore nullable, while every displayed paper still comes from the Exa publications search.
