Any public api I can check jsonp ajax call?

Question

Besides Twitter, I wonder if anyone knows of any public web API with which I can try ajax call using jsonp protocol?

Answer 1

jsfiddle provides an echo tool that is quite useful: http://doc.jsfiddle.net/use/echo.html

JSONP url: http://jsfiddle.net/echo/jsonp/

Data must be provided through GET. jsFiddle will answer all the data in the request. It uses a URL with a host and protocol since it is loaded from a different domain. callback and delay are not returned.

jsonp delay function callback name optional; its time in seconds after which data should be returned
