What does this tool do?

Explains any HTTP status code — its meaning and when you will see it.

Why would I use it?

You are debugging an API error and want the official meaning.
You are writing docs or error handling.
You want a quick reference without searching.

Real-life example

Input

Output

429 Too Many Requests — rate limiting; Retry-After suggests when to retry.

Each code has a short, practical explanation.

Input → Process → Output → Next

Input: Type a code or browse the list.
Process: YAS returns the status line and practical notes.
Output: Meaning and typical cause.
Next action: Use the right code in your own API responses.

Common mistakes

Using 4xx for server faults (use 5xx).
Returning 200 for errors (breaks clients).
Misreading 3xx as errors — they are redirects.

What the result means

The class (1xx–5xx) tells you the general outcome.

Privacy & security

Your input is sent to YAS infrastructure because the tool requires server-side processing or public network queries. Input is not stored.
