So far as I understood, we see right here one transaction (in "tx": [...]), on 50 BTC, the transaction id (txid). Having this knowledge, how can I get the enter/output handle utilizing e.g. the identical bitcoin-cli or RPC API equal (in keeping with the doc)?

Does coinbase in vin means Block Reward?
How from vout (or wherever else) get the handle we often see (1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa)?

I attempted bitcoin-cli getrawtransaction ... (as right here) however the output is unclear to me.

If bitcoin-cli is unable to supply that – then every other manner?
