# 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
|
|
}
|
|
});
|
|
```
