What's Included in this SDK
BitIndex API v3
Documentation: https://www.bitindex.network/developers/api-documentation-v3.html
Endpoints
Please note: Currently only the "main" (mainnet) endpoint is supported.
Endpoints:
- https://api.bitindex.network/api/v3/main (Mainnet)
Example get a transaction on 'Mainnet':
Promises vs. Callback
Both await and callback styles are supported for all methods.
Example:
// Await style with promises
var result = await bitindex.address.getUtxos('12XXBHkRNrBEb7GCvAP4G8oUs5SoDREkVX');
// Callback style
bitindex.address.getUtxos('12XXBHkRNrBEb7GCvAP4G8oUs5SoDREkVX', function(result) {
// ...
});
Address
address.getUtxos
Get unspent outputs
var result = await bitindex.address.getUtxos('12XXBHkRNrBEb7GCvAP4G8oUs5SoDREkVX');
// Or specify multiple addresses to retrieve Utxo's for all addresses...
var result = await bitindex.address.getUtxos(['17d9np3mtaz13kYdePwc2Cufd6dMoNjWib', '1XeMYaLJX6rhXcRe2XtGh6hgstgXwZ5SD']);
