That transaction is valid and confirmed.
"Unspent" in the right-hand column means that the outputs have not been spent. The funds are still sitting in the 1965... and 144f... addresses and have not been moved out of those addresses.
If one or both of those addresses belong to you (i.e. you generated them with your own wallet and have the private key(s)), ...

Bitcoind does not index transactions for non-wallet addresses. If you wish to build this yourself, you will need to:
Enable txindex=1 in your bitcoin.conf
Rescan the chain
Set up blocknotify and then parse the chain block by block, building an index of which outputs have been spent, and which haven't, and which addresses are involved in each transaction

Apparently this command only works for addresses in my wallet, and moreover, there is apparently no way for the reference client to do this query for addresses not in the wallet (doh :-/)

listunspent will list all unspent outputs of addresses the wallets controls, it will not work for any arbitrary address.
You can importaddress to add any address as a watch-only address, but this may take some time as your node will need to rescan the blockchain to find all associated transactions. Also note that when you use importaddress, you will not be ...

Bitcoin Core does not store the information for all addresses as that would be computationally expensive and not very useful. For you to get this data, the address needs to be part of your wallet. So you must add the address to the wallet using importaddress and allow Bitcoin Core to rescan the blockchain. It will then find all of the transactions related to ...

If you have sent and received Bitcoin before, then this output is likely a change output.

This is a historical oddity.
In the past, Bitcoin Core would report the list of participating keys in a multisig addresses by listing the addresses for those keys. This was both confusing (addresses and keys are distinct things), but also unreliable, as the full public keys were not always knowm (when P2Sh was introduced). You can safely assume you won't ...

The first issue, with getbalance, is a known issue which will be fixed in the next release. You can see the pull request for it here: https://github.com/bitcoin/bitcoin/pull/14602
The latter, though, I cannot seem to replicate. To my knowledge, listunspent has not been modified in version 0.17, and it seems to work as expected when I test on the command ...

To create a new transaction (with createrawtransaction) you will require a previous unspent vout - i.e. a UTXO, which is the result of the listunspent command. This will be the input of the transaction. The output of the transaction will be created on the fly, based on the amount and destination address. A transaction fee is likely necessary, and is ...

You will need to contact Changelly customer service to have the excess btc returned to you.

Your question:
How to get the available balance of a specific address using blockchain.info
The description for the /balance API:
List the balance summary of each address listed.
So use /balance.
/unspent lists all the outputs for all addresses you provide in one big list, not grouped by address. But since you're just adding them all anyway, it ...

You do not need the uxto of the other address to be able to send it BTC. You just need the address.
If you want to list unspents of an address you don't have the keys for, I don't think bitcoind can help you. However, you can use explorers like blockchain.info: https://blockchain.info/unspent?active=35QEobWVUKjMY2HwKATYYQXRGzXJvdXQCy&format=html (there'...
