• You can add the [blocked_test_url] shortcode whereever you want to provide a search form for blocked URLs.
• In the settings, you'll need to provide a page ID to which the search form redirects in order to display the results. On this page, please add the [blocked_test_url] shortcode.
• You can add the [blocked_display_stats] shortcodes anywhere to display the statistics of all blocked sites (test provided by API against a set of the 100 most important websites ranked on Alexa)

Simple PHP implementation

require "lib/BlockedUrl.php";

$blocked = new BlockedUrl ( '<API_KEY>', '<API_EMAIL>', '<URL_TO_TEST>', <HOST> );
$blocked = new BlockedUrl ( '<API_KEY>', '<API_EMAIL>', '<URL_TO_TEST>', <HOST>, false ); // disable SSL peer verification

// push your URL to network, and fetch response
my $pushed = $blocked->push_request()->push_response();

// yields:
// array(
//       "hash"    => string,
//       "queued"  => bool,
//       "success" => bool,
//       "uuid"    => int
// )

// retrieve URL status
$status = $blocked->get_status()->status_response();

// yields:
// array(
//       "url-status" => string( "ok"|"blocked" ),
//       "categories" => array( string ),
//       "results"    => array(
//            blocktype               => 'what',
//            category                => 'ever',
//            first_blocked_timestamp => '2015-03-19 12:39:48',
//            last_blocked_timestamp  => '2015-03-19 12:39:48',
//            network_name            => 'Fake ISP Ltd',
//            status                  => 'ok',
//            status_timestamp        => '2015-04-30 22:46:54'
//               ...
//       )
// )

METHODS

constructor( string $api_key, string, $api_email, string $url, string $host, boolean $ssl_verification = true )

$api_key, $api_email, $host and the $url are mandatory parameters. Set $ssl_verification to false if you wish to call to hosts with self-signed SSL certificates.

The $host is either an IP or hostname string identifying the machine on which the server to query runs on. Currently only API Version 1.2 is supported. URL maming scheme is:

https://<HOST>/1.2/<API-ENDPOINT>

whereas "1.2" and supported endpoints are hard-coded.

url( )

Sets/gets the URL to check.

push_request()

Performs a push of the instance's url to the network. Results can be retrieved from push_response().

Returns $this, throws exception on all errors.

push_response()

Returns the parsed JSON answer of last successful push_request()

get_daily_stats([ int ])

Calls to daily-stats facility. Returns object instance. To get reponse, call to daily_stats_response() afterwards

$blocked->get_daily_stats( 10 )->daily_stats_response()

get_status()

Tries to get the status for current URL from network. If this fails with a 404 status it tries to push the URL to the network first, then retries. Result can be retrieved from status_response().

Returns $this, throws exception on all other errors.

status_response()

Returns the parsed JSON answer of last successful get_status()

daily_stats_response()

Returns the parsed JSON anwer of last successful get_daily_stats()
