Deepak, thank you for the API compilation. I am sad though, that you included the insults api. As educated people, I doubt nurturing lower insticts and behaviours promoting harshness and violence 'for fun' or 'testing' helps anyone be happy.

Thank you for your feedback. I appreciate your concerns regarding the inclusion of the insults API. You're absolutely right that promoting positive and respectful behavior is important, especially in a professional context. I'll make sure to be more mindful of this in the future. If there's anything specific you would like to see or avoid in my future compilations, please let me know.
