SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Paper discovery is slow when you have to guess which database has the best coverage and then manually verify results, so this Skill accelerates literature search and identifier lookups to return comprehensive matches quickly.

Core Features & Use Cases

  • Multi-database scholarly search: Searches across PubMed, PMC (full text), bioRxiv, medRxiv, arXiv, OpenAlex, Crossref, Semantic Scholar, CORE, and Unpaywall to reduce missing relevant work.
  • Identifier-based retrieval and OA verification: Resolves queries by DOI/PMID/arXiv/OpenAlex IDs and checks open-access availability (including best OA PDF links when possible).
  • Citation graph and metadata enrichment: Supports citation/references-oriented lookups and returns structured JSON responses for downstream analysis.

Quick Start

Ask the assistant to look up papers about "Wardrop equilibrium" and include open-access PDF availability when available.

Frequently Asked Questions about paper-lookup

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I find scholarly papers across multiple databases at once?▼

You can search across 10 academic databases including PubMed, arXiv, OpenAlex, and bioRxiv simultaneously. The Skill executes targeted REST API calls based on your query to aggregate metadata and reduce the chance of missing relevant literature.

Can I look up a paper by DOI or arXiv ID and check for open access PDFs?▼

Yes, identifier-based retrieval resolves queries using DOI, PMID, arXiv, or OpenAlex IDs. It verifies open-access availability by querying the Unpaywall API and retrieves the best available OA PDF links for the matched papers.

What is the best way to query citation graphs and references for biomedical preprints?▼

Citation graph lookups query biomedical and preprint indexes like bioRxiv, medRxiv, and Semantic Scholar. This returns structured JSON responses containing reference metadata for downstream analysis of citation networks.

Does this paper search tool work with Crossref and Semantic Scholar APIs?▼

Yes, the search covers both Crossref and Semantic Scholar alongside CORE and OpenAlex. It selects the appropriate database set, reads the corresponding endpoint reference docs, and performs the API calls to return raw JSON responses.

What format are the search results returned in when querying multiple academic indexes?▼

Search results are returned as raw JSON responses plus a list of the queried databases and endpoints. This structured format supports direct downstream analysis and metadata enrichment for literature reviews.
