Insight

Description

bitcore.transport.explorers.Insight is a simple agent to perform queries to an Insight blockchain explorer. The default servers are https://insight.bitpay.com and https://test-insight.bitpay.com, hosted by BitPay Inc. You can (and we strongly suggest you do) run your own insight server. For more information, head to https://github.com/bitpay/insight-api

There are currently two methods implemented (the API will grow as features are requested): getUnspentUtxos and broadcast.

Retrieving Unspent UTXOs for an Address (or set of)

var insight = new Insight();
insight.getUnspentUtxos('1Bitcoin...', function(err, utxos) {
  if (err) {
    // Handle errors...
  } else {
    // Maybe use the UTXOs to create a transaction
  }
});

Broadcasting a Transaction

var insight = new Insight();
insight.broadcast(tx, function(err, returnedTxId) {
  if (err) {
    // Handle errors...
  } else {
    // Mark the transaction as broadcasted
  }
});
