Create an account at https://beta.openai.com/playground . You get $18 of free credits, and generating small snippets with the most powerful language model costs only a cent.
Another great option is https://textsynth.com/playground.html (made by the very impressive developer Fabrice Bellard - of linux in javascript and world pi digit calculation fame). He deserves some money funneled through that site for his efforts over the decades (and the output is about as good as gpt-3 imo).
