Frequently asked questions
What is the difference between tools.voiddo.com/http and httpstatuses.com?
httpstatuses.com is a comprehensive reference for all HTTP status codes — 60+ codes, short descriptions, and links to the relevant RFC sections. It is the go-to tool when you need to quickly look up what a specific code means or find the right code for a response. tools.voiddo.com/http focuses differently: it covers the 8 most commonly misunderstood status codes and response headers with full RFC quotes, real-world causes for when you see that code, and fix notes for when you may have returned the wrong code.
Does httpstatuses.com include real-world examples or fix notes?
No. httpstatuses.com provides the official name, a short description, and a link to the RFC section for each code. It does not include real-world scenarios, reasons why a code might be returned incorrectly, or advice on which code to use in a specific API design situation. tools.voiddo.com/http adds those practical layers for the 8 most-confusing codes.
Does tools.voiddo.com/http cover all HTTP status codes?
No. tools.voiddo.com/http deliberately covers only the 8 most frequently confused codes — like 401 vs 403, 200 vs 204, 302 vs 307 — and common response headers. For a full list of all status codes (1xx through 5xx), httpstatuses.com or the MDN HTTP reference is the right resource.
Which tool should I use to find the right HTTP status code for my API?
If you know which range you need (2xx, 3xx, 4xx, 5xx) and want to browse all options, httpstatuses.com is better — it gives the full list at a glance with a direct URL per code. If you are debugging a code your API returned and want to understand when it is correct vs incorrect and what the RFC actually says, tools.voiddo.com/http goes deeper on the most commonly misused codes.
Does httpstatuses.com explain response headers?
httpstatuses.com focuses on status codes only. tools.voiddo.com/http includes explainers for key response headers — Cache-Control, Content-Type, Location, Retry-After — alongside the status code coverage, since headers and codes are often misunderstood together in the same debugging session.
