Scholar Bibliographic APIs

This post contains my notes about web APIs to access bibliographic data, mostly for the sake of open-access.

Meta APIs

Meta-APIs gather content from different bibliographic repositories.

BASE

• Documentation: https://api.base-search.net/
• Indexed repositories: https://www.base-search.net/about/en/about_sources.php
• Example: https://api.base-search.net/cgi-bin/BaseHttpSearchInterface.fcgi?func=PerformSearch&format=json&query=10.1162/neco.2006.18.10.2509 (requires registration of IP address)
• Output: JSON

Unpaywall/oadoi Can be used to find open-access URLs based on a DOI

• Documentation: https://unpaywall.org/products/api
• Indexed repositories: https://api.oadoi.org/data/sources.csv
• Example: http://api.oadoi.org/v2/10.1145/3238147.3240474?email=m@f
• Output: JSON

Dissemin

• Documentation: https://dev.dissem.in/api.html
• Indexed repositories: https://dev.dissem.in/datasources.html
• Example: https://dissem.in/api/10.1145/1509307.1509309
• Output: JSON

CORE

• Documentation: https://core.ac.uk/services#api
• Example: https://core.ac.uk/api-v2/articles/search/bengio?apiKey=XXYYZZ
• Output: JSON

Semantic Scholar

• Documentation: https://api.semanticscholar.org/api-docs/
• Example:
  • https://api.semanticscholar.org/v1/paper/10.1038/nrn3241
  • https://api.semanticscholar.org/graph/v1/paper/10.1038/nrn3241
  • https://api.semanticscholar.org/graph/v1/author/2240541463
• Output: JSON
• Original points:
  • contain “citation velocity” and “highly influential citations”
  • graph/v1/paper/ contains “tldr” summary and “embedding”
  • SemanticScholar makes their entire corpus available (in JSON format). They also offer API keys so that you can avoid the rate-limiting of the API.
  • Wrapper Python library: https://github.com/danielnsilva/semanticscholar

OpenAire

• Examples:
  • DOI query: http://api.openaire.eu/search/publications?doi=10.1016/j.jss.2019.01.069&format=json
  • Author query:
    • json: http://api.openaire.eu/search/publications?author=monperrus&format=json
• Documentation: https://api.openaire.eu/api.html

DBLP

• Examples:
  • by key conf/icst/AlshammariAHB24.xml https://dblp.org/rec/conf/icst/AlshammariAHB24.xml (also supports rdf, nt, ttl, ris, bib and html by changing suffix)
    • json wrapper
  • query: https://dblp.org/search/publ/api/?q=amplification
• Documentation: https://dblp.uni-trier.de/faq/How+to+use+the+dblp+search+API

OpenAlex (“An open and comprehensive catalog of scholarly papers, authors, institutions” by OurResearch)

• Examples:
  • DOI query: https://api.openalex.org/works/https://doi.org/10.7717/peerj.4375
  • Author query: https://api.openalex.org/authors/https://orcid.org/0000-0002-1298-3089
• Documentation: https://docs.openalex.org/

Repository APIs

arXiv

• Examples:
  • by arxiv identifier https://export.arxiv.org/api/query?id_list=1205.6361 (returns ATOM/RSS)
  • by arxiv identifier JSON https://www.monperrus.net/martin/arxiv-json.py?id=2409.18952
  • https://export.arxiv.org/api/query?max_results=2000&search_query=doi:10.11s45/2896995.2896996

HAL

• Examples:
  • DOI query:
  • Author query: https://api.archives-ouvertes.fr/search/?wt=json&q=authFullName_s:%22Martin+Monperrus%22&rows=1000 (json)
• Documentation: https://api.archives-ouvertes.fr/docs

Publisher APIs

• Crossref
  • Documentation: https://github.com/CrossRef/rest-api-doc
    • Our API doesn’t support exact string matching for any field except for singleton fields (doi, issn, etc)
    • If the API call includes a query, then the sort order will be by the relevance score. If no query is included, then the sort order will be by DOI update date.
  • Example by DOI: http://api.crossref.org/works/10.1016/j.ydbio.2017.03.003
  • Example by Journal ISSN: <https://api.crossref.org/journals/0098-5589, https://api.crossref.org/journals/0098-5589/works
  • Example by Conference ISSN https://api.crossref.org/works?filter=issn:0270-5257
  • Example via title https://api.crossref.org/works?query.title='betroot'
  • Example via orcid https://api.crossref.org/works?filter=orcid:0000000335053383
  • a list of ISSNs associated with conference series https://api.crossref.org/works?filter=type:proceedings-article&facet=issn:*&rows=0
• Elsevier
  • Example https://api.elsevier.com/content/article/PII:S0950584916300714?httpAccept=text/xml (example json output)
    • can be used without API key, but “x-els-status: WARNING - Unauthorized request results in minimized metadata response”
  • Scopus endpoint: https://api.elsevier.com/content/search/scopus?apiKey=xyz&query=john
• IEEE Explore
  • Documentation
  • https://ieeexploreapi.ieee.org/api/v1/search/articles?querytext=author:monperrus&apiKey=foobar
  • by article id https://ieeexploreapi.ieee.org/api/v1/search/articles?article_number=10093112&apiKey=xxxx result
• IEEE Computer sociey

  • Endpoint: https://api.clarivate.com/api/wos/
  • Example: https://gist.github.com/monperrus/213571c6551004252ba3936d6ac8201a
  • Documentation: https://developer.clarivate.com/
• Springer/SpringerNature
  • Documentation: https://dev.springernature.com/docs/api-endpoints/
  • Example: https://api.springernature.com/meta/v2/json?api_key=YOUR_API_KEY&q=doi:YOUR_DOI
• ACM does not provide any API AFAIK

Other APIs

Chorus Chorus is about funding. The search service enables users to discover articles reporting on research from a given funder. The dashboard service enables funders, institutions, researchers, publishers, and the public to keep track of public-access compliance.

• /institution/:id/histories Allows the user to download the metadata found in our Institution Dashboards
• http://search.chorusaccess.org/funders Allows the user to find the Crossref Funder Names and Funder IDs of all the Agencies monitored by CHORUS. Updated every 24 hours.
