Search papers and analyze citation graphs via OpenAlex and CrossRef APIs

  • Calls curl; reaches api.openalex.org and api.crossref.org
  • Tasks that involve Citation management

What it does

Semantic Scholar API is an agent skill from wentorai/research-plugins. Search papers and analyze citation graphs via OpenAlex and CrossRef APIs

Its SKILL.md is about 1.3k 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 and Citation management. It works with Semantic Scholar. 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
  • Tasks that involve Citation management

Example prompts

  • “/semantic-scholar-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
    • api.crossref.org
    • wentor.ai

    Also links to:

    • docs.openalex.org
    • github.com

    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

Semantic Scholar API loads about 1.3k tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 442 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~23
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

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.

Search papers and analyze citation graphs via OpenAlex and CrossRef APIs

OpenAlex & CrossRef API Guide

Overview

OpenAlex is a free, open catalog of the global research system, indexing over 250 million academic works across all fields of science. It provides structured access to papers, authors, institutions, concepts, and citation networks. OpenAlex is the successor to Microsoft Academic Graph and is maintained by OurResearch (the team behind Unpaywall).

CrossRef is the official DOI registration agency for scholarly content, providing metadata for over 150 million DOIs across all publishers and disciplines. Together, OpenAlex and CrossRef provide comprehensive coverage for academic search, citation analysis, and bibliometric research.

Both APIs are free to use without authentication. OpenAlex requests a polite User-Agent header; CrossRef requests a User-Agent with contact email for access to the polite pool (faster rate limits).

Authentication

No authentication is required for either API.

OpenAlex: Include a User-Agent header for polite access:

User-Agent: ResearchPlugins/1.0 (https://wentor.ai)

CrossRef: Include a User-Agent header with contact email for polite pool:

User-Agent: ResearchPlugins/1.0 (https://wentor.ai; mailto:dev@wentor.ai)

  • Response: JSON with full bibliographic metadata including title, authors, journal, dates, references count, and citation count.

Rate Limits

OpenAlex: No strict rate limit, but use polite User-Agent header. Recommended: max 10 requests per second. The API returns HTTP 429 when limits are exceeded.

CrossRef: Without polite pool: ~50 requests per second. With polite pool (contact email in User-Agent): higher limits. The API returns HTTP 429 when limits are exceeded.

Common Patterns

Build a Citation Network

Retrieve a paper and find all works that cite it:

bash
# Get paper details
curl "https://api.openalex.org/works/W2741809807"

# Get works citing this paper, sorted by citation count
curl "https://api.openalex.org/works?filter=cites:W2741809807&sort=cited_by_count:desc&per_page=20"
Find Influential Papers on a Topic

Search for highly cited works on a topic:

bash
curl "https://api.openalex.org/works?search=graph+neural+networks&sort=cited_by_count:desc&per_page=20"
Batch Paper Lookup via CrossRef

Search CrossRef for papers matching a query, sorted by citation count:

bash
curl "https://api.crossref.org/works?query=graph+neural+networks&sort=is-referenced-by-count&order=desc&rows=20"

Questions about Semantic Scholar API

What does Semantic Scholar API do?

Search papers and analyze citation graphs via OpenAlex and CrossRef APIs. Semantic Scholar API is an agent skill from wentorai/research-plugins.

When should I use Semantic Scholar API?

Semantic Scholar API fits situations like: tasks that involve Academic paper search; tasks that involve Citation management.

How do I install Semantic Scholar API in Claude Code?

Run `npx skills add wentorai/research-plugins --skill semantic-scholar-api -a claude-code`. Or copy the skill folder (skills/literature/search/semantic-scholar-api in wentorai/research-plugins) into .claude/skills/semantic-scholar-api in your project. Claude Code loads it when a task matches its description.

How do I install Semantic Scholar API in Codex?

Run `npx skills add wentorai/research-plugins --skill semantic-scholar-api -a codex`. Or copy the skill folder (skills/literature/search/semantic-scholar-api in wentorai/research-plugins) into .agents/skills/semantic-scholar-api in your project. Codex loads it when a task matches its description.

Can I use Semantic Scholar API in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add wentorai/research-plugins --skill semantic-scholar-api -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/semantic-scholar-api, .gemini/skills/semantic-scholar-api, .github/skills/semantic-scholar-api and .opencode/skills/semantic-scholar-api in your project.

What does Semantic Scholar API need to run?

Going by SKILL.md and its folder, Semantic Scholar API needs the command-line tools its instructions call (curl).

Does Semantic Scholar API access the network?

SKILL.md names 5 domains. In commands or code: api.openalex.org, api.crossref.org and wentor.ai; the agent is likely to contact these when it follows the instructions. As links in the text: docs.openalex.org and github.com. This is read from the text; nothing was executed.

Is Semantic Scholar API safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
