Get citation count at a given time

[VJalili]

Is there any method or API to get citation count at a given time? e.g., how many times the article with DOI XYZ was cited through 2016 (since it's publication date to 2016).

You can use the Citation Overview API to accomplish this: https://pybliometrics.readthedocs.io/en/stable/examples/CitationOverview.html

Using that method I get 403 Client Error.

I am using the following code (from the documentation page):

from pybliometrics.scopus import CitationOverview
co = CitationOverview("2-s2.0-84930616647", start=2015, end=2017)

and I get the following error:

Traceback (most recent call last):
  File ".\main.py", line 2, in <module>
    co = CitationOverview("2-s2.0-84930616647", start=2015, end=2017)

Yes, see the second sentence in the docs. You need special permission by Scopus for this API. Your local Scopus salesperson can help you.
