I’ve seen this pattern too many times to ignore. You write a clean cURL request, hit enter, get a nice 200 back, JSON looks good, and suddenly everyone relaxes like the job is done. cURL is brilliant at that moment. It is simple, direct, brutally honest. You send exactly what you wrote and the server responds. No magic, no abstraction, just raw truth. And that’s exactly why developers trust it. If something works in cURL, you know what was sent. But here’s the uncomfortable part: it only proves that one exact request worked once. Nothing more. Real APIs don’t live in that perfect scenario. Fields go missing, values change, types break, tokens expire, payloads get messy, and clients behave in ways nobody planned for. And suddenly that clean request doesn’t mean much anymore. You could write dozens of variations by hand in cURL, but let’s be honest, nobody wants to sit there crafting broken payloads all day just to see if something explodes.
