The numbers are the frame member numbers. All four count as heavy requests for [[SimTX API/Control session#Rate limits|rate limiting]]. Each carries a <code>request_id</code> that its response echoes. A refused request is answered with [[SimTX API/Packets/Error|Error]] carrying that <code>request_id</code> and a message that says what to fix; the session continues.

Browsing works anonymously. Publishing requires an authenticated control session: obtain a [[SimTX API/Game tickets|game ticket]] with role <code>control</code> (which itself requires <code>catalog.publish</code>) and present it in the hello.
