Thanks alot
Adding XCP assets is not possible using the blockscan.com API, as far as I know.
You’ll need to install/run counterparty, and use that API itself. See http://counterparty.io/docs/counterpartyd/ for the API docs
@CoinTrack Are you talking about tracking, i.e. providing balances and values, or actually creating assets? The blockscan.com API makes it pretty simple to do the former but doesn’t support the latter. The Address API section at http://blockscan.com/api is probably mainly what you and your coder need.
