-title: Insight Explorer
-description: Provides an interface to fetch information about the state of the blockchain from a trusted Insight server.
----
-# 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)
-
-```javascript
-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
-
-```javascript
-var insight = new Insight();
-insight.broadcast(tx, function(err, returnedTxId) {
-  if (err) {
-    // Handle errors...
-  } else {
-    // Mark the transaction as broadcasted
-  }
-});
-```
