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.
We are temporarily scaling back our no-cost access program in order to prioritize resources in light of the coronavirus pandemic. To learn more about what this means for your research, visit our Support portal.
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. Before requesting access, please learn more below about what information our data does and does not include.
Altmetric is a proud partner of the International Society for Scientometrics and Informetrics. ISSI members applying for no-cost access to Altmetric data are eligible for special consideration. To learn more, read the press release and consider joining ISSI.
Available data formats
All of the following data formats include mention data from the 13+ 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||
|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.
