Researcher Data Access Program
Providing free access to Altmetric data for those who study how research is shared and communicated online
Supporting the scientometrics community
Altmetric is committed to helping others drive forward the field of altmetrics research through investigating our data. That’s why we offer our data free of charge to those who wish to understand patterns in scholarly communication across the Web.
Data access is granted only for one-time, limited duration research projects. If you are interested in using our data for evaluative purposes, including for building dashboards, please check out our products listing.
Researchers who wish to enroll in the Researcher Data Access Program must agree to a number of terms (described fully in the Program application form), including making one’s work Open Access, abiding by our official branding guidelines and attribution requirements, and sharing resulting presentations and publications with Altmetric.
Before requesting access, please learn more below about what information our data does and does not include.
We offer free access in several formats suited to all levels of technical expertise.
Available data formats
All of the following data formats include mention data from the 12+ million research outputs we’ve found mentions for online, to date.
|Type||Conditions of use||What can I do with it?|
|Altmetric Details Page API – Counts Only||
|Altmetric Details Page API – Counts Only, with API key||
|Raw database snapshot (JSON)||
|Custom data retrieval ($)||
What does the data include?
Altmetric tracks detailed metrics and mentions for discussions of research outputs (e.g. datasets, journal articles, monographs) on the Web. We capture all mentions where a research output with a compatible persistent identifier and adequate metadata has been linked to in any of the sources we track. The bulk of our data contains mentions from 2011 onward. For more details on our data collection practices, please visit our knowledge base.
What doesn’t the data include?
Our data does not include social media topics and hashtags unless they are associated with discrete research outputs. We also do not track downloads and pageviews, due to concerns over data reliability.
