SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Researchers often need to locate scholarly papers across multiple databases, verify metadata, DOIs/PMIDs, and OA/full-text availability. This skill provides a unified workflow to query biomedical and multidisciplinary databases, gather results, and present raw responses along with source databases. It aims to streamline comprehensive literature discovery, citation checks, and open-access verification.

Core Features & Use Cases

  • Cross-database discovery: search PubMed, PMC, OpenAlex, Crossref, arXiv, bioRxiv/medRxiv, Semantic Scholar, and Unpaywall for a given topic.
  • Metadata consolidation: return DOIs/PMIDs, authors, publication venues, dates, and OA status, with raw API responses.
  • Open access verification: identify OA PDFs or full texts and surface direct OA links when available.
  • Use Case: perform a topic search and compare results across databases to build a literature map.

Quick Start

Ask me to search for papers on a topic and I will fetch results from PubMed, PMC, OpenAlex, Crossref, arXiv, bioRxiv/medRxiv, Semantic Scholar, and Unpaywall in parallel and return structured metadata.

FAQPage Schema
How do I search for scholarly papers across multiple databases at once?

Searching for scholarly papers across multiple databases is done by running parallel queries against ten sources including PubMed, OpenAlex, Crossref, arXiv, bioRxiv, medRxiv, Semantic Scholar, and Unpaywall to return consolidated structured metadata for your topic.

Can I find open access PDFs and full text links using DOI or PMID lookups?

Yes, DOI and PMID lookups retrieve open access status and surface direct OA PDF or full-text links by querying databases like Unpaywall alongside metadata sources, returning both citation details and open access availability.

What is the best way to verify open access availability for academic articles?

The best way to verify open access availability for academic articles is to query Unpaywall and other scholarly databases in parallel, which identifies OA PDFs, full texts, and surfaces direct open access links when available.

How to consolidate metadata like authors, publication venues, and dates from different scholarly sources?

Consolidating metadata like authors, publication venues, and dates from different scholarly sources is achieved by applying database-specific search strategies across ten databases in parallel and returning structured metadata along with the raw API responses.

Does cross-database scholarly search work for biomedical preprints and multidisciplinary topics?

Yes, cross-database scholarly search works for biomedical preprints and multidisciplinary topics by querying arXiv, bioRxiv, medRxiv, PubMed, OpenAlex, and Semantic Scholar simultaneously to gather and compare structured results across all sources.

What are the limitations of using a unified scholarly search across multiple APIs?

A limitation of unified scholarly search across multiple APIs is that results depend on each database's specific search strategies and API response structures, meaning raw responses and metadata fields may vary in completeness across the ten queried sources.
