Check-Host API PHP Library

A lightweight, lightning-fast, and feature-complete PHP 8+ wrapper for the Check-Host.cc API. Full API reference: check-host.cc/docs. A bundled OpenAPI 3.0.3 / Swagger spec ships at swagger.yaml for codegen / offline browsing.

Seamlessly integrate global network diagnostics into your backend. Perform remote Ping, MTR, DNS, HTTP, TCP and UDP checks from multiple worldwide locations—straight from your PHP application. Checks from 60+ locations worldwide.

Features

• Zero Dependencies: Built purely on the native PHP cURL extension. No Guzzle, no Symfony HTTP Client, zero package bloat.
• Bulletproof Payloads: Strictly utilizes POST requests for all active monitoring endpoints. This completely eliminates nasty URL-encoding issues with complex hostnames or custom UDP payloads.
• Modern & Clean: Written for PHP 8.1+ with full type hinting and clean structure.
• Smart Authentication: API Key auto-injection. Configure your key once during initialization, and the core SDK seamlessly handles all authentication payloads under the hood.

Requirements

• PHP: ^8.1
• ext-curl and ext-json

Installation

Ensure you have PHP 8.1+ installed. You can install the package directly from Packagist using Composer:

composer require check-hostcc/check-host-api-php

Manual Installation

If you prefer not to use Composer, you can download the source code and require the class files directly:

require_once '/path/to/src/Exceptions/CheckHostException.php';
require_once '/path/to/src/CheckHost.php';

Quickstart

require 'vendor/autoload.php';

use CheckHostCc\CheckHostApi\CheckHost;

// Initialize the client. The API Key is optional.
// Without an API key, standard public rate limits apply.
// $checkHost = new CheckHost('YOUR_API_KEY_HERE');
// Or leave empty: new CheckHost()
$checkHost = new CheckHost();

// Example: Retrieve all current nodes
$locations = $checkHost->locations();
print_r($locations);

Complete API Reference & Examples

This library supports both minimal invocations and detailed, options-rich requests for every endpoint. All failures (network issues, API errors, rate limits) throw a CheckHostException.

Common Options Used in Examples

• region: Array of Nodes or ISO Country Codes (e.g. ['DE', 'NL']) or Continents (e.g. ['EU']).
• repeatchecks: Number of repeated probes to perform per node for higher accuracy (Live Check).
• timeout: Connection timeout threshold in seconds. Supported by methods where a timeout is applicable (e.g., HTTP, TCP).

Information & Utilities

Get My IP

Returns the requesting client's public IPv4 or IPv6 address.

$ip = $checkHost->myip();

Get Locations

Fetches a dynamic list of all currently active monitoring nodes across the globe.

$nodes = $checkHost->locations();

Host Info (GeoIP/ASN)

Retrieves detailed geolocation data, ISP information, and ASN details.

// Minimal Example
$info = $checkHost->info('check-host.cc');

WHOIS Lookup

Performs a WHOIS registry lookup.

// Minimal Example
$whois = $checkHost->whois('check-host.cc');

---

Active Monitoring (POST Tasks)

Monitoring endpoints initiate tasks asynchronously and return a Task Object array containing an uuid. Use the report() method (documented below) to fetch the actual results.

Ping

Dispatches ICMP echo requests to the target from global nodes.

// Minimal Example
$pingMin = $checkHost->ping('8.8.8.8');

// Max Example (With options)
$pingMax = $checkHost->ping('8.8.8.8', [
    'region' => ['DE', 'NL'],
    'repeatchecks' => 5,
    'timeout' => 5
]);

DNS

Queries global nameservers for specific DNS records.

// Minimal Example
$dnsMin = $checkHost->dns('check-host.cc');

// Max Example (With options - TXT Record)
$dnsMax = $checkHost->dns('check-host.cc', [
    'querymethod' => 'TXT', // A, AAAA, MX, TXT, SRV, etc.
    'region' => ['US', 'DE']
]);

TCP

Attempts to establish a 3-way TCP handshake on a specific destination port.

// Minimal Example (Target, Port)
$tcpMin = $checkHost->tcp('1.1.1.1', 443);

// Max Example (With options)
$tcpMax = $checkHost->tcp('1.1.1.1', 80, [
    'region' => ['DE', 'NL'],
    'repeatchecks' => 3,
    'timeout' => 10
]);

UDP

Sends UDP packets to a specified target and port.

// Minimal Example (Target, Port)
$udpMin = $checkHost->udp('1.1.1.1', 53);

// Max Example (With custom hex payload and options)
$udpMax = $checkHost->udp('1.1.1.1', 123, [
    'payload' => '0b', // NTP Request Hex
    'region' => ['EU'],
    'repeatchecks' => 2,
    'timeout' => 5
]);

HTTP

Executes an HTTP/HTTPS request to the target to measure TTFB and latency.

// Minimal Example
$httpMin = $checkHost->http('https://check-host.cc');

// Max Example (With options)
$httpMax = $checkHost->http('https://check-host.cc', [
    'region' => ['US', 'DE'],
    'repeatchecks' => 3,
    'timeout' => 10
]);

MTR

Initiates an MTR (My Traceroute) diagnostic.

// Minimal Example
$mtrMin = $checkHost->mtr('1.1.1.1');

// Max Example (With protocols, IP forced, and options)
$mtrMax = $checkHost->mtr('1.1.1.1', [
    'repeatchecks' => 15,
    'forceIPversion' => 4,     // 4 or 6
    'forceProtocol' => 'TCP',  // default is ICMP
    'region' => ['DE', 'US']
]);

---

Fetching Results

Report

Fetches the compiled report and real-time statuses from a previously initiated monitoring check (Ping, TCP, HTTP, etc.) using its unique uuid. Wait 1-2 seconds after starting a check before polling. Longer checks with multiple repeats take one check per second and can be requested multiple times.

// The check UUID is returned by any monitoring method above
$taskUuid = 'c0b4b0e3-aed7-4ae2-9f53-7bac879697cb';

// Fetch the result payload
$report = $checkHost->report($taskUuid);
