FAQ
- What does this HTTP status codes tool do?
- It lets you search and browse HTTP status codes by number or keyword, grouped by category (1xx through 5xx). Use it for quick reference during API work.
- Does this tool validate or enforce HTTP protocol?
- No. It is a local reference lookup only. It does not validate requests, responses, or enforce any protocol rules.
- Are all HTTP status codes included?
- The tool includes common codes developers encounter. The IANA registry and RFC 9110 define the full official set.
- How do I search by phrase vs by code?
- Type a number to match by code (exact or prefix). Type words to match the status name or description. Both are case-insensitive.
