Include

// Node
var bitindex = require('bitindex-sdk').instance();
<!-- Browser -->
<script src="dist/bundle.min.js"></script>
<script language="javascript">
    // ...
    var bitindex = new BitIndex();
    var result = await bitindex.address.getUtxos('12XXBHkRNrBEb7GCvAP4G8oUs5SoDREkVX');
    console.log('result', result);
</script>

Prerequisites

  • No API authentication needed except for Xpub calls
  • For Xpub calls get an API key at BitIndex

What's Included in this SDK

BitIndex API v3

Documentation: https://www.bitindex.network/developers/api-documentation-v3.html

New: BitIndex is now Bitcore Insight-API compatible. The Insight-API compatibile methods are indicated with a comment.

Endpoints

Please note: Currently only the "main" (mainnet) endpoint is supported.

Endpoints:

Example get a transaction on 'Mainnet':

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

Example get a transaction on 'Testnet':

https://api.bitindex.network/api/v3/test/tx/0849b19c494ffe2d74fe4a7930f11e74a3ad10607f47e61bc06a892f89bcee67

Example get a transaction on 'Scaling Testnet (STN)':

https://api.bitindex.network/api/v3/stn/tx/d677e2a67fd960cf85489a365bbdc3b5e5de2ccc91f7552d096ccebfaf3e584f

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']);

Callback Example

Notify at the webhook endpoint callback url when an address or child address of an xpub receives a payment.

Callbacks for addresses are received at your configured URL.

Note: You can receive up to multiple callbacks in any order. Make sure to check the 'confirmations' parameter and always use the highest 'confirmations' your application has seen before.

It is possible that old webhooks are in transit with a lower 'confirmations' than what you have received before.

Note: You should be able to rely on payments of 3 confirmations.

Always check with the > and < operators since it cannot be guaranteed that you will receive a webhook with exactly 3 confirmations (it could be 4, 5 or more).
