Hello,

no there is nothing in XMPP to check if a user exists. This is by design and for security reasons.
But the register function will return an 409 error if the username is in use.

sample error packet:

<iq type='error' id='reg2'>
<query xmlns='jabber:iq:register'>
    <username>bill</username>
    <password>m1cro$oft</password>
    <email>billg@bigcompany.com</email>
</query>
<error code='409' type='cancel'>
    <conflict xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'/>
</error>
</iq>

Older server may return another error code. So just check them all.
You should get this error in OnRegisterError Handler.

let me know if this helps you.
