What it does
Openalex API is an agent skill from wentorai/research-plugins. Query the OpenAlex catalog of scholarly works, authors, and institutions
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Research & Science, covering Academic paper search. The repository describes itself as: 350+ academic research skills, MCP configs, and plugins for Research-Claw and AI agents. The licence is MIT.
When your agent uses it
- Tasks that involve Academic paper search
Example prompts
- “/openalex-api”
What it can do on your machine
Read from SKILL.md and the folder at commit bf44b3c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
curl
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
api.openalex.org
Also links to:
docs.openalex.org
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Openalex API loads about 1.5k tokens when it runs. Until then it costs about 21 tokens; SKILL.md has 509 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

OpenAlex API Guide
Overview
OpenAlex is a free, open catalog of the global research system. It indexes over 250 million scholarly works, 90 million authors, 100,000 institutions, and 65,000 concepts. Created by the nonprofit OurResearch as a replacement for Microsoft Academic Graph, OpenAlex provides comprehensive bibliometric data for academic research analysis.
The API serves as a powerful tool for researchers conducting systematic literature reviews, bibliometric analyses, and research landscape mapping. It covers works across all academic disciplines, linking papers to their authors, institutions, concepts, and citation networks. Each entity in OpenAlex has a persistent identifier (OpenAlex ID) and is enriched with metadata from CrossRef, ORCID, ROR, and other authoritative sources.
OpenAlex is entirely free to use. No API key is required, though providing a contact email in the mailto parameter grants access to the polite pool with faster response times and higher rate limits.
Authentication
No authentication required. For better rate limits and access to the polite pool, include your email in requests:
https://api.openalex.org/works?mailto=your@email.comThe polite pool provides significantly faster responses and is recommended for all production usage.
Core Endpoints
Works: Search Scholarly Publications
- URL:
GET https://api.openalex.org/works - Parameters:
Param Type Required Description search string No Full-text search across titles and abstracts filter string No Structured filters (e.g., publication_year:2024, cited_by_count:>100) sort string No Sort field: cited_by_count, publication_date, relevance_score page integer No Page number for pagination (default: 1) per_page integer No Results per page (default: 25, max: 200) mailto string No Email for polite pool access - Example:
bash curl "https://api.openalex.org/works?search=large+language+models&filter=publication_year:2024&sort=cited_by_count:desc&per_page=10&mailto=user@example.com" - Response: JSON with
resultsarray containingid,title,doi,publication_date,cited_by_count,authorships,concepts,open_accessstatus, andabstract_inverted_index.
Authors: Search Researcher Profiles
- URL:
GET https://api.openalex.org/authors - Parameters:
Param Type Required Description search string No Name-based author search filter string No Filters (e.g., works_count:>50, last_known_institution.id) sort string No Sort field: works_count, cited_by_count, h_index per_page integer No Results per page (default: 25, max: 200) - Example:
bash curl "https://api.openalex.org/authors?search=Geoffrey+Hinton&mailto=user@example.com" - Response: JSON with
resultsarray containingid,display_name,orcid,works_count,cited_by_count,h_index,last_known_institution, andx_concepts.

Institutions: Search Academic Organizations
- URL:
GET https://api.openalex.org/institutions - Parameters:
Param Type Required Description search string No Institution name search filter string No Filters (e.g., country_code:US, type:education) sort string No Sort field: works_count, cited_by_count per_page integer No Results per page - Example:
bash curl "https://api.openalex.org/institutions?search=MIT&mailto=user@example.com" - Response: JSON with institution details including
id,display_name,ror,country_code,type,works_count, andcited_by_count.
Concepts: Browse Research Topics
- URL:
GET https://api.openalex.org/concepts - Parameters:
Param Type Required Description search string No Concept name search filter string No Filters (e.g., level:0 for top-level concepts) per_page integer No Results per page - Example:
bash curl "https://api.openalex.org/concepts?filter=level:0&per_page=50&mailto=user@example.com" - Response: JSON with concept hierarchy,
works_count, and related concepts.
Rate Limits
Without the mailto parameter: 10 requests per second, 100,000 requests per day. With the mailto parameter (polite pool): significantly higher throughput. The API uses HTTP 429 responses when limits are exceeded. Implement exponential backoff for production usage.
Common Patterns
Citation Analysis for a Paper
Retrieve all works that cite a specific paper by its DOI:
curl "https://api.openalex.org/works?filter=cites:W2741809807&sort=cited_by_count:desc&per_page=25&mailto=user@example.com"Institutional Research Output
Analyze publication trends for a specific institution:
curl "https://api.openalex.org/works?filter=institutions.id:I136199984,publication_year:2024&group_by=open_access.is_oa&mailto=user@example.com"Topic Landscape Mapping
Explore how a concept connects to others in the research landscape:
curl "https://api.openalex.org/concepts/C41008148?mailto=user@example.com"References
