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

• Original points:
  • contain “citation velocity” and “highly influential citations”
