Hi,
not exactly sure what you mean but the answer is rather no.
More detailed answer:
First of all, JDownloader can only get a list of supported hosts of a multihost when you add an account.
For most of all, you will only get a list if that account is a premium account.
...so let's say you would own a (premium) account for all multihosts JDownloader supports:
You could do the following:
1. Add all accounts to JD.
2. Grab all supported hosts of all multihosts using an
EventScripter script or the
myjd API.
