PHP Tone Checker

This example uses PHP's cURL extension.

<?php

$apiKey = getenv('SAPLING_API_KEY');
if (!$apiKey) {
    throw new RuntimeException('Set SAPLING_API_KEY first.');
}

$payload = json_encode([
    'text' => 'Really stoked about this! Will it be ready by next week?',
], JSON_THROW_ON_ERROR);

$request = curl_init('https://api.sapling.ai/api/v1/tone');
curl_setopt_array($request, [
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => $payload,
    CURLOPT_HTTPHEADER => [
        'Authorization: Bearer ' . $apiKey,
        'Content-Type: application/json',
    ],
    CURLOPT_RETURNTRANSFER => true,
]);

$body = curl_exec($request);
if ($body === false) {
    throw new RuntimeException(curl_error($request));
}

$status = curl_getinfo($request, CURLINFO_RESPONSE_CODE);
curl_close($request);

if ($status < 200 || $status >= 300) {
    throw new RuntimeException("Sapling API error {$status}: {$body}");
}

echo $body;
