OpenAI API error: "You didn't provide an API key. You need to provide your API key in an Authorization header using Bearer auth" – WordPress

I am creating a PHP script to access Open Ai’s API, to ask a query and get a response.

I am getting the following error:

You didn’t provide an API key. You need to provide your API key in an
Authorization header using Bearer auth (i.e. Authorization: Bearer
YOUR_KEY)

…but I thought I was providing the API key in the first variable?

Here is my code:

$api_key = "sk-U3B.........7MiL";

$query = "How are you?";

$url = "https://api.openai.com/v1/engines/davinci/jobs";

// Set up the API request headers
$headers = array(
    "Content-Type: application/json",
    "Authorization: Bearer " . $api_key
);

// Set up the API request body
$data = array(
    "prompt" => $query,
    "max_tokens" => 100,
    "temperature" => 0.5
);

// Use WordPress's built-in HTTP API to send the API request
$response = wp_remote_post( $url, array(
    'headers' => $headers,
    'body' => json_encode( $data )
) );

// Check if the API request was successful
if ( is_wp_error( $response ) ) {
    // If the API request failed, display an error message
    echo "Error communicating with OpenAI API: " . $response->get_error_message();
} else {
    // If the API request was successful, extract the response text
    $response_body = json_decode( $response['body'] );
    //$response_text = $response_body->choices[0]->text;
    var_dump($response_body);
    // Display the response text on the web page
    echo $response_body;

    All Engines endpoints are deprecated.

    Deprecated

    This is the correct Completions endpoint:

    https://api.openai.com/v1/completions

    Working example

    If you run test.php the OpenAI API will return the following completion:

    string(23) "

    This is indeed a test"

    test.php

    <?php
    $ch = curl_init();

    $url = 'https://api.openai.com/v1/completions';

    $api_key = 'sk-xxxxxxxxxxxxxxxxxxxx';

    $post_fields = '{
        "model": "text-davinci-003",
        "prompt": "Say this is a test",
        "max_tokens": 7,
        "temperature": 0
    }';

    $header  = [
        'Content-Type: application/json',
        'Authorization: Bearer ' . $api_key
    ];

    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $header);

    $result = curl_exec($ch);
    if (curl_errno($ch)) {
        echo 'Error: ' . curl_error($ch);
    }
    curl_close($ch);

    $response = json_decode($result);
    var_dump($response->choices[0]->text);
?>

    I’ve seen reports that you can’t use your free credits until you put a credit card on file. Idk if that’s true, but I had a very similar issue until I added mine.
