Use this link to see what Blockchain.info supports
Standard convention is described fully in the types.json file in the link above.
simply require the npm module at the top of the file
var blockchaininfoClient =
api_code: "your api code here"
you may specify the options you wish to make a call like so:
blockchaininfoClient.Addresses.Unspents(["address 1", "address 2", ...], callback);
- Blockchain.info does not support unconfirmed balance so in Addresses.Summary, both unconfirmedBalance and confirmedBalanace will be null; however, balance will represent the confirmed balance of the address.
- Blockchain.info does not support unconfirmed unspent outputs, so Addresses.Unspents will not display unspents that do not have at least one confirmation
