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':

https://api.bitindex.network/api/v3/main/tx/96b3dc5941ce97046d4af6e7a69f4b38c48f05ef071c2a33f88807b89ab51da6

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']);
