I've just had my attention drawn to this feature of the Better Bibtex
plugin for Zotero:

https://zotplus.github.io/better-bibtex/cayw.html

So, Better Bibtex now supports an HTTP endpoint that generates various
kinds of citations.I'm not sure if that's helpful only for creating
citation keys, or if it gives a way to use Zotero  Erik, I was wondering if
you had seen it and whether you have a sense of how much this overlaps with
your work in zotxt.  And org: I thought it was worth pointing out another
possible method for integrating with Zotero.
