Questions
How many status codes does it cover?
Every code registered with IANA, about 60 across the five classes (1xx to 5xx). That includes the WebDAV codes and 418 "I'm a teapot".
What is the difference between 401 and 403?
401 means the request has no valid credentials, so signing in may fix it. 403 means the server knows who you are and still refuses.
Can I search by name instead of number?
Yes. Type a word like "redirect", "unauthorized" or "rate limit" to see every matching code. Type a number to see that code in full.
