JSON 2 JSONP
JSON 2 JSONP is a single-endpoint utility that wraps any JSON URL in a JSONP callback on the fly, letting old-style script-tag cross-domain requests read JSON that has no CORS headers of its own. Pass the target url and a callback name as query parameters and it returns application/javascript, cached for 4 hours; the service itself has been run by JoomlaWorks since 2006 and needs no signup or API key.
