SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Researchers often need to locate scholarly papers across many databases. This Skill automates selecting the right databases, querying their REST APIs, and returning results with provenance.

Core Features & Use Cases

  • Multi-database search: Determine the best databases for a query and run REST API calls to retrieve metadata, DOIs, abstracts, and open-access links.
  • Unified results with provenance: Return raw JSON/XML responses from each database along with the exact endpoints used.
  • Open science coverage: Access PubMed, PMC, bioRxiv, medRxiv, arXiv, OpenAlex, Crossref, Semantic Scholar, CORE, and Unpaywall for comprehensive literature discovery.
  • Format-aware retrieval: Handle database-specific formats (e.g., arXiv Atom XML) and standard JSON responses.
  • Use Case: A user searches for "CRISPR gene therapy" and aggregates metadata from multiple sources to compare DOIs, authors, and OA status.

Quick Start

Find papers on CRISPR gene therapy across PubMed, PMC, OpenAlex, and Crossref.

How do I search scholarly papers across multiple databases via REST APIs?▼

To search scholarly papers across multiple databases via REST APIs, this Skill selects relevant sources like PubMed and arXiv, queries their endpoints, and returns structured metadata with provenance.

What is the best way to retrieve open-access metadata from PubMed and OpenAlex?▼

Retrieving open-access metadata from PubMed and OpenAlex is done by calling their REST endpoints through this Skill, which returns raw JSON responses alongside the exact endpoints used for provenance.

How do I handle arXiv Atom XML responses when searching literature databases?▼

Handling arXiv Atom XML responses during literature database searches is automated by this Skill, which parses non-JSON formats and provides a structured output of results and sources.

Can I query Crossref and Semantic Scholar simultaneously for academic literature?▼

Yes, you can query Crossref and Semantic Scholar simultaneously. This Skill determines the relevant databases for your query and executes REST API calls to aggregate DOIs, abstracts, and OA links.

Does searching multiple scholarly databases respect API rate limits?▼

Searching multiple scholarly databases respects API rate limits by automating the selection and querying of REST endpoints, ensuring format-aware retrieval while returning structured results and provenance.
