Quick start

<?php

curl_setopt_array($ch, [
    CURLOPT_POST => true,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_TIMEOUT => 180,
    CURLOPT_HTTPHEADER => [
        "X-API-Key: " . getenv("SIMILARIQ_API_KEY"),
        "Content-Type: application/json",
    ],
    CURLOPT_POSTFIELDS => json_encode(["domain" => "salesforce.com", "limit" => 100]),
]);
$data = json_decode(curl_exec($ch), true);
foreach (array_slice($data["competitors"], 0, 10) as $c) {{
    echo "{{$c['rank']}}. {{$c['company']}} ({{$c['domain']}}) — {{$c['matchScore']}}\n";
