Hey I have not quite Dev but important questions, I’m new to TON but I like it.

Questions:
How can you tell if a jetton contract has had admin revoked
How can you tell if more jettons can or cannot be minted
How can you tell where the JSON data for the jetton is stored? (or is that for the image only)
Is there an API i can call for these types of things
Is TON compatible with ethers.js?
Can you tell if a Jetton has been minted with custom codes as opposed to TonMinter?

Thanks, I appreciate the help.
