For example, to find yearly citations of article with PMID 15926897:

esearch -db pubmed -query 15926897 \
  | elink -name pubmed_pmc_refs -target pmc \
  | efetch -format docsum \
  | xtract -pattern DocumentSummary -element PubDate \
  | cut -f1 -d" " | sort | uniq -c

Results in:

  6 2006
  3 2008
  3 2009
  1 2011
  3 2012
  3 2013
  1 2015
  3 2016
  3 2017
  2 2018

please is there an api equivalent of this code. I want to be able to generate this using a single api call ie. https://eutils.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&linkname=pubmed_pubmed_citedin&id=2040531 or if there's an api call that can retrieve not only the pmids that cited a particular pmid but also other info for the cited pmids (i.e. publication date)
