What it does
Europe Pmc API is an agent skill from wentorai/research-plugins. Search biomedical and life sciences literature via Europe PMC
Its SKILL.md is about 1.6k 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 Literature review. It works with PubMed. 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 Literature review
Example prompts
- “/europe-pmc-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:
curljq
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:
ebi.ac.uk
Also links to:
europepmc.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
Europe Pmc API loads about 1.6k tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 548 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.

Europe PMC API Guide
Overview
Europe PMC (PubMed Central) is a free, comprehensive biomedical literature database maintained by the European Bioinformatics Institute (EMBL-EBI) as part of a network of 32 European funders. It provides access to over 40 million biomedical and life sciences publications, including abstracts from PubMed/MEDLINE, full-text articles from PubMed Central, patents from the European Patent Office, and preprints from biomedical preprint servers.
Europe PMC extends beyond PubMed by integrating additional European content, preprints, and rich text-mined annotations. It provides links to biological databases (UniProt, Protein Data Bank, etc.), grant information from funders, and citation data. The annotation features include gene/protein mentions, disease names, organism identifiers, and chemical entities extracted via machine learning.
The API is free, requires no authentication, and supports 10 requests per second. It returns JSON or XML and offers advanced query syntax with field-specific searches, boolean operators, and date range filters.
Authentication
No authentication required. The Europe PMC API is fully open. No API key, registration, or email is needed. The API enforces a rate limit of 10 requests per second per IP address. Including a descriptive User-Agent header is considered good practice.
Core Endpoints
Search: Full-Text Literature Search
- URL:
GET https://www.ebi.ac.uk/europepmc/webservices/rest/search - Parameters:
Param Type Required Description query string Yes Search query (supports field codes: TITLE, AUTH, JOURNAL, DOI, etc.) format string No Response format: json (default) or xml resultType string No lite (default) or core (includes full abstract and metadata) pageSize integer No Results per page (default: 25, max: 1000) cursorMark string No Cursor for deep pagination (use nextCursorMark from response) sort string No Sort field: RELEVANCE, CITED, DATE (default: RELEVANCE) synonym boolean No Enable MeSH synonym expansion (default: true) - Example:
bash curl "https://www.ebi.ac.uk/europepmc/webservices/rest/search?query=CRISPR+AND+cancer&format=json&resultType=core&pageSize=10&sort=CITED+desc" - Response: JSON with
hitCount,nextCursorMark, andresultList.resultarray. Each result containsid,source(MED, PMC, PPR, PAT),pmid,pmcid,doi,title,authorString,journalTitle,pubYear,abstractText,citedByCount,isOpenAccess, andfullTextUrlList.

Citations: Papers Citing a Publication
- URL:
GET https://www.ebi.ac.uk/europepmc/webservices/rest/{source}/{id}/citations - Parameters:
Param Type Required Description source string Yes Source database: MED (PubMed), PMC, PPR (preprint), PAT (patent) id string Yes The publication ID (PMID, PMCID, etc.) format string No json or xml page integer No Page number (default: 1) pageSize integer No Results per page (default: 25) - Example:
bash curl "https://www.ebi.ac.uk/europepmc/webservices/rest/MED/33116299/citations?format=json&pageSize=10" - Response: JSON with
hitCountandcitationList.citationarray containing citing publication metadata.

GET https://www.ebi.ac.uk/europepmc/webservices/rest/{source}/{id}/references - Parameters:
Param Type Required Description source string Yes Source database id string Yes The publication ID format string No json or xml page integer No Page number pageSize integer No Results per page - Example:
bash curl "https://www.ebi.ac.uk/europepmc/webservices/rest/MED/33116299/references?format=json&pageSize=50" - Response: JSON with
referenceList.referencearray containing reference metadata.
Rate Limits
The API enforces a rate limit of 10 requests per second per IP address. There is no daily request cap. Exceeding the rate limit returns HTTP 429. For bulk data access, Europe PMC provides OAI-PMH harvesting, FTP bulk downloads, and SPARQL endpoint access. Cursor-based pagination (using cursorMark) is required for retrieving beyond the first 10,000 results.
Common Patterns
Systematic Review Search
Perform a structured biomedical search with MeSH terms and date filters:
curl -s "https://www.ebi.ac.uk/europepmc/webservices/rest/search?query=(TITLE:immunotherapy+AND+TITLE:melanoma)+AND+(PUB_YEAR:[2022+TO+2026])&format=json&resultType=core&pageSize=25&sort=CITED+desc" | jq '.resultList.result[] | {title: .title, journal: .journalTitle, year: .pubYear, citations: .citedByCount, oa: .isOpenAccess}'Find Preprints Related to a Topic
Search specifically in the preprint sources indexed by Europe PMC:
curl -s "https://www.ebi.ac.uk/europepmc/webservices/rest/search?query=(SRC:PPR)+AND+large+language+models+AND+biology&format=json&pageSize=10" | jq '.resultList.result[] | {title: .title, source: .source, year: .pubYear, doi: .doi}'Build a Citation Map for a Key Paper
Retrieve both citations and references to map a paper's scholarly context:
# Get papers that cite the target
curl -s "https://www.ebi.ac.uk/europepmc/webservices/rest/MED/33116299/citations?format=json&pageSize=50" | jq '.citationList.citation | length'
# Get papers referenced by the target
curl -s "https://www.ebi.ac.uk/europepmc/webservices/rest/MED/33116299/references?format=json&pageSize=100" | jq '.referenceList.reference | length'References
