user87689: Is there any way to get history balance of an address. Balance is unspent transaction outputs (UTXOs). 
I am using BCOIN node. 
Bcoin has given a API for /coin/address/:address but it is giving current balance as a result instead of history.

user50821: Looking at the docs, you're using the HTTP api incorrectly. 
Try this in your terminal. Make sure to define or change the $url variable. 
address0='RQKEexR9ZufYP6AKbwhzdv8iuiMFDh4sNZ';
address1='RHpAA3ZmmmWF6FW8qSfaEvh1jR1nUmVYnj';

curl $url/coin/address \
  -H 'Content-Type: application/json' \
  -X POST \
  --data '{ "addresses":[ "'$address0'", "'$address1'" ]}'
