I'm using dozens of clients for to scan all the different blockchains. The main query I need to do is getting address balances. Do you have a recommendation for a REST or Websocket API that supports a lot of coins?
Bonus points if the API can retrieve balances for multiple addresses at once.
I have one recommendation, have a look at (
https://chainz.cryptoid.info/api.dws), it has lot of altcoins. the only problem is that it returns JSON object/data.
What? Why did this end up in Bitcoin Forum > Economy > Marketplace > Service Discussion?
This is programming question.
It's probably because you're asking of a service/site that provides API to query balance of a address?
