Use Laravel with OpenAI to validate inappropriate content

Recently I stumbled across OpenAI Moderations API which gives you a way to query OpenAI in order to detect if input text contains inappropriate content such as hate, violence, etc.

API is completly free - you just need to create an OpenAI account and issue a fresh API token.

Since I'm primary a Laravel PHP Framework developer, I decided to make a package which will provide a way to validate request payload fields against OpenAI Moderations API.


Standard Composer package installation:

composer require rcerljenko/laravel-openai-moderation
Enter fullscreen mode Exit fullscreen mode


  1. Publish config and translation files.
php artisan vendor:publish --provider="RCerljenko\LaravelOpenAIModeration\LaravelOpenAIModerationServiceProvider"
Enter fullscreen mode Exit fullscreen mode
  1. Set your OpenAI API key and enable package via newly created config file => config/openai.php

  2. Use provided rule with your validation rules.


namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;
use RCerljenko\LaravelOpenAIModeration\Rules\OpenAIModeration;

class StoreText extends FormRequest
  * Determine if the user is authorized to make this request.
 public function authorize(): bool
  return true;

  * Get the validation rules that apply to the request.
 public function rules(): array
  return [
   'text' => ['required', 'string', new OpenAIModeration],
Enter fullscreen mode Exit fullscreen mode

And that's it! Your content can now be validated with powerfull (and yet free) OpenAI Moderations API.
