]);

// Execute the request
$response = curl_exec($curl);
$httpCode = curl_getinfo($curl, CURLINFO_HTTP_CODE);

// Check for errors
if (curl_errno($curl)) {
    echo 'cURL Error: ' . curl_error($curl);
} else {
    // Process the response
    $result = json_decode($response, true);
    
    if ($httpCode == 200 && isset($result['success']) && $result['success']) {

Model Pricing

Usage Cost

$0.045 Cost Per Generation

Cost Per Generation is a pricing model where you’re charged based on each individual output the model generates. Instead of billing for compute time, you pay a fixed cost for every generation request, regardless of how long it takes. This makes costs predictable since each generated result incurs its own set rate.

Features Included:

Full API access
Web UI usage
Output in multiple formats
Commercial usage rights
