Multi Domain Search

Search across 8 knowledge domains from a single agent — not 8 web engines, 8 completely different databases. One query can search the live web, academic papers, preprints, biomedical literature, chemical compounds, scholarly works, government datasets, and the dictionary simultaneously.

How to call endpoints

Search strategy

When the user asks you to search for something, decide which domains are relevant and fan out across them. Don't search every domain for every query — be smart about it.

General knowledge questions — start with web_search and web_qna, add scholarly_search if the topic has academic depth.

Scientific or medical questions — lead with biomedical_search and papers_search, supplement with preprints_search for cutting-edge work, then web_search for recent news coverage.

Chemistry questions — start with chemistry_compound, then biomedical_search for related drug/pharma research, then papers_search for fundamental science.

Data and statistics — check demographics_datasets for government data, scholarly_search for published studies with data, web_search for recent reports.

Word meanings and language — use dictionary_define and dictionary_synonyms for precise definitions, then web_search for usage context.

Comprehensive research — fan out across all relevant domains, then synthesize. Start broad, then drill into the most promising domain.

Always tell the user which domains you searched and what each returned. Cite sources with DOIs, PMIDs, URLs, or arXiv IDs.

Available search domains (8 engines, 15 endpoints)

1. Live Web (Tavily)

4. Preprints (arXiv)

Search Preprints — $0.002 Search arXiv for the latest preprints before they're formally published. Cutting-edge research.

bash {baseDir}/scripts/search.sh GET /api/v1/research/preprints/search '{"query":"diffusion models image generation","category":"cs.CV"}'

Recent by Category — $0.002 Browse the latest preprints in any arXiv category.
