HTTP API

With the Coinhive HTTP API you can get the number of hashes solved for a user account on your website, withdraw hashes, verify tokens and programmatically create shortlinks.

Using this API requires a secret key (see Settings » Sites). As the name implies, this key should be kept secret and should never be exposed to your users. The HTTP API should only ever be called from the server side, i.e. from PHP, NodeJS, Ruby, Python scripts running on your own server.

You should never call the Coinhive HTTP API from the client side.

Your secret key can be passed with each API call as a GET or POST parameter, depending on the required method for the endpoints.

The API returns a JSON encoded object for each request. All responses contain a boolean success property. In case success is false, an error property will be present, describing why the operation failed.

PHP Class

We developed a tiny PHP class to make using our HTTP API a bit easier.
Download the CoinHiveAPI class from github

The class has just two methods for get and post requests. You can use it like this:

// Instantiate the class with your secret key
$coinhive = new CoinHiveAPI('YOUR_SECRET_KEY');

// Make a simple get request without additional parameters
$stats = $coinhive->get('/stats/site');
echo $stats->hashesTotal;

// Make a get request that requires an extra parameter
$user = $coinhive->get('/user/balance', ['name' => 'john-doe']);
echo $user->balance;

// Make a post request
$link = $coinhive->post('/link/create', [
	'url' => 'http://google.com', 
	'hashes' => 1024
]);

if ($link->success) {
	echo $link->url;
}
