1. In Bitcoin core we used to call bitcoin-cli getwalletinfo through command line, and through json rpc curl request curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getwalletinfo", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:8332/. Do we have same thing in Armory, if let me know some example of it.
With armoryd, all calls assume the context that a current wallet is selected. To get data from other wallets, you need to select the relevant one. The first wallet armoryd loads is set as the default one.
There's a somewhat large armoryd example you can find here:

Unfortunately I don't know how much of it still works, as it was written in 2014.
It would be armoryd.conf
