== Usage ==
APY supports three types of requests: GET, POST, and JSONP. Using GET/POST are possible only if APY is running on the same server as the client due to cross-site scripting restrictions; however, JSONP requests are permitted in any context and will be useful. Using curl, APY can easily be tested:
<code>
<pre>curl -G --data "lang=kaz-tat&modes=morph&q=алдым" http://localhost:2737/perWord</pre>
</code> It can also be tested through your browser or through HTTP calls. Unfortunately, curl does '''not''' decode JSON output by default and to make testing easier, a APY Sandbox is provided in the SVN with [[Apertium-html-tools]].
