Update: Etsy API no longer requires jQuery
Recently I posted a link to an Etsy API client library that requires jQuery to operate. This is no longer the case: as part of another project involving the YUI library—which doesn’t have baked-in JSONP support—I went about implementing a simple JSONP service. I ported it over and now the library is freestanding. The link is at the same place, http://nickol.us/code/etsyapi.js
