API Error Decoder – Because "500 Internal Server Error" Isn't Helpful
Let's be honest: debugging HTTP errors is half the job, and half the frustration.
You hit an API, and back comes 401 Unauthorized. Great. But why? Did the token expire? Was it malformed? Did you forget to include it in the header? Or was it the wrong kind of token altogether? The response rarely tells you. You end up guessing, Googling, checking docs, and still wasting 20 minutes on something that should take 2.
That’s why I built API Error Decoder.
It’s a simple tool that takes common (and not-so-common) HTTP status codes and turns them into plain English explanations with actionable steps. No fluff. No jargon. Just: "Here’s what likely went wrong, and here’s how to fix it."
For example:
-
429 Too Many Requests→ "You’ve hit a rate limit. Wait 60 seconds or request a higher quota from the API provider." -
400 Bad Request→ "Check your JSON syntax, required fields, or data types. The server couldn’t parse your payload."
It covers status codes from 4xx and 5xx, with context-specific fixes based on real debugging patterns.
There’s a free tier that gives you access to all basic error explanations. No login required.
If you want more — like detailed API-specific guidance (e.g., common pitfalls with Stripe, Auth0, or AWS APIs), bulk error lookup, or integration tips for your dev team — there’s a Pro plan for $9/month. It’s just enough to cover hosting and keep the lights on.
I didn’t build this to replace docs or debugging skills. I built it to save time when you’re stuck on an error that should be obvious but isn’t.
