SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires requests.

What problem does it solve? Researchers need comprehensive academic metadata beyond what arXiv or Semantic Scholar offer, including open citation graphs, institutional affiliations, and funding information, without paying for closed databases. ## Core Features & Use Cases - OpenAlex API Search: Query 250M+ works with filters for year, work type, open access status, minimum citations, and sort order. - Rich Metadata Retrieval: Returns abstracts, topics, keywords, DOIs, open access status with PDF links, and citation counts. - Work Lookup by Identifier: Fetch a specific paper by DOI or OpenAlex ID for cross-referencing with arXiv and Semantic Scholar. - Use Case: A researcher studying wireless communication trends runs a filtered search for open-access journal articles from 2020-2023 with at least 50 citations, then cross-references the top results in Semantic Scholar. ## Quick Start Ask the assistant to search OpenAlex for papers on your topic, for example by saying "use openalex to search for machine learning papers from 2023 onward sorted by citations".

Frequently Asked Questions about openalex

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

FAQPage Schema
How do I search academic papers with the OpenAlex API?▼

Run the openalex_fetch.py script with a search query, for example python3 openalex_fetch.py search "machine learning" --max 10. You can add filters like --year 2023-, --type article, --open-access, --min-citations 50, and --sort citations.

OpenAlex vs Semantic Scholar for literature search?▼

OpenAlex provides fully open citation data, institutional affiliations, funding information, and broader cross-discipline coverage of 250M+ works. Semantic Scholar updates citation counts faster and offers influential citation metrics, making it better for CS-focused research.

Does OpenAlex require an API key?▼

No, OpenAlex works without an API key for basic use, but rate limits are very low. A free API key allows 10,000 list calls and 1,000 search calls per day, and setting the OPENALEX_EMAIL environment variable enables the faster polite pool.

How do I look up a paper by DOI in OpenAlex?▼

Run python3 openalex_fetch.py work followed by the DOI, such as python3 openalex_fetch.py work "10.1109/TWC.2024.1234567". You can also pass an OpenAlex work ID like W2741809807 to retrieve the same structured metadata.

Why does the OpenAlex search fail with a script not found error?▼

The skill requires the openalex_fetch.py helper resolved from .aris/tools/, tools/, or $ARIS_REPO/tools/. Rerun the install script, export ARIS_REPO, or copy the helper into tools/, and ensure the requests package is installed.
