Background
----------
The [FindStat][1] project encourages contributors to provide references for combinatorial statistics.

I am currently redesigning the way such references are processed.  In future, a contributor should only type something like [[arxiv:1234.5678]] or [[MO168885]], without providing any further information.  The program then will fetch author and title from the various websites.  This was (relatively) easy for the arXiv, but for mathoverflow citations (which occur a lot, by nature of the site), I'm hitting a problem:

Question
--------
Which request should my program send to mathoverflow.net to get the bibtex, which is so well hidden behind the share button.

Rephrased: what I'm after is something analogous to a link like:

http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=2011arXiv1111.3349P&data_type=BIBTEX

which serves the bibtex for arXiv articles.
