    {
        "entity": "2",
        "expression": "'Vin Number'>71006"
    }

The message body is a JSON string containing two key-value pairs: the first, ``entity``, is the library ID to check against; the second, ``expression``, is the expression to check.

    200, Success
    500, Server error

A successful response contains the expression transformed into XML.

The request above would result in the following response:

.. code-block:: http

    HTTP/1.1 200 OK
    Content-type: text/xml

    <?xml version="1.0" ?>
    <expr>
        <text>'Vin Number'&gt;71006</text>
        <gt>
            <var>Vin Number</var>
            <int>71006</int>
        </gt>
    </expr>
