PHP Example

Use the RBLXValue API in PHP projects, WordPress plugins, or web apps.

Basic Item Lookup

<?php
define('RBLXVALUE_KEY', 'rbx_your_key_here');

function rblx_get_item(string $slug): ?array {
    $ch = curl_init("https://rblxvalue.com/api/v1/items?slug=" . urlencode($slug));
    curl_setopt_array($ch, [
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_HTTPHEADER     => ['X-Api-Key: ' . RBLXVALUE_KEY],
        CURLOPT_TIMEOUT        => 5,
    ]);
    $data = json_decode(curl_exec($ch), true);
    curl_close($ch);
    return $data['item'] ?? null;
}

$item = rblx_get_item('seer');
if ($item) {
    $src_a = (int)($item['value_source_a'] ?? 0);
    $src_b = (int)($item['value_source_b'] ?? 0);
    $est   = (int)round(($src_a + $src_b) / 2);
    echo "{$item['name']}: " . number_format($est) . " (demand: {$item['demand']}/10)";
}

Set Lookup

function rblx_get_set(string $slug): ?array {
    $ch = curl_init("https://rblxvalue.com/api/v1/sets?slug=" . urlencode($slug));
    curl_setopt_array($ch, [
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_HTTPHEADER     => ['X-Api-Key: ' . RBLXVALUE_KEY],
        CURLOPT_TIMEOUT        => 5,
    ]);
    $data = json_decode(curl_exec($ch), true);
    curl_close($ch);
    return $data['set'] ?? null;
}

$set = rblx_get_set('chroma-evergreen-set');
if ($set) {
    echo "{$set['name']}: " . number_format($set['total_value']) . " total\n";
    foreach ($set['items'] as $item) {
        echo "  - {$item['name']}: " . number_format($item['value']) . "\n";
    }
}

Profile Lookup

function rblx_get_profile(string $username): ?array {
    $ch = curl_init("https://rblxvalue.com/api/v1/profile?username=" . urlencode($username));
    curl_setopt_array($ch, [
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_HTTPHEADER     => ['X-Api-Key: ' . RBLXVALUE_KEY],
        CURLOPT_TIMEOUT        => 5,
    ]);
    $data = json_decode(curl_exec($ch), true);
    curl_close($ch);
    return $data['profile'] ?? null;
}

$profile = rblx_get_profile('UN6107617');
if ($profile) {
    echo "{$profile['display_name']} — ";
    echo $profile['inventory_public']
        ? number_format($profile['total_value']) . " inventory value"
        : "Private inventory";
}

Trade Calculator

function rblx_trade_calc(array $your_slugs, array $their_slugs): array {
    $get_val = function(string $slug): int {
        $item = rblx_get_item($slug);
        if (!$item) return 0;
        $a = (int)($item['value_source_a'] ?? 0);
        $b = (int)($item['value_source_b'] ?? 0);
        return (int)round(($a + $b) / 2);
    };

    $your_total  = array_sum(array_map($get_val, $your_slugs));
    $their_total = array_sum(array_map($get_val, $their_slugs));

    return [
        'your_total'  => $your_total,
        'their_total' => $their_total,
        'difference'  => $their_total - $your_total,
        'fair'        => abs($their_total - $your_total) / max($your_total, 1) < 0.1,
    ];
}

$result = rblx_trade_calc(['seer', 'ginger'], ['chroma-scythe']);
echo $result['fair'] ? 'Fair trade' : 'Unfair trade';
echo " (difference: " . number_format($result['difference']) . ")";
