    curl_setopt($init, CURLOPT_CUSTOMREQUEST, 'POST');
    $data = json_encode([
        "email" => $req['email'],
        "username" => $req['username'],
        "password" => password_hash($req['password'], PASSWORD_DEFAULT),
    ]);
    curl_setopt($init, CURLOPT_POSTFIELDS, $data);

I suspect that what this is doing and what you think it is doing are two different things, and further that the Content-Type header doesn’t match this clause.
