Use this skill whenever the user wants to query OpenAlex for works, authors, institutions, sources, topics, publishers, or funders. Trigger on phrases like "search OpenAlex for X", "find papers in OpenAlex", "OpenAlex works by author Y", "get institution metadata from OpenAlex", "look up this DOI in OpenAlex", "how many works does institution X have in OpenAlex", or any request that specifically involves the OpenAlex API or database.

# OpenAlex API Skill Query the [OpenAlex](https://openalex.org) open scholarly metadata catalog via its REST API using curl. **Base URL:** `https://api.openalex.org` **Auth:** API key required (free at https://openalex.org/settings/api). Pass as `?api_key=KEY`. Store in env var `OPENALEX_API_KEY` and use `api_key=$OPENALEX_API_KEY` in queries. --- ## Entity Endpoints | Endpoint | Description | |----------|-------------| | `/works` | Scholarly documents (articles, books, datasets) | | `/authors` | Researcher profiles with disambiguated identities | | `/sources` | Journals, repositories, conferences | | `/institutions` | Universities, research organizations | | `/topics` | Subject classifications (3-level hierarchy) | | `/publishers` | Publishing organizations | | `/funders` | Funding agencies | | `content.openalex.org/works/{id}.pdf` | PDF download ($0.01 each) | Singleton lookups are free (e.g., `/works/W2741809807`). List/filter queries cost $0.0001; search queries cost $0.001. --- ## Critical: Two-Step ID Resolution Names are ambiguous — never filter by display name directly. Resolve to an OpenAlex ID first, then use that ID in filters. ```bash # WRONG /works?filter=author_name:E

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill openalex --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
