What does this tool do?
Look up an HTTP status code's standard text, category and concise description from a local reference. Inputs: HTTP status code. Outputs: Status code, Status text, Status category, Description.
How to use it?
Enter http status code, then choose “Lookup”. Clear removes inputs and results and restores initial options.
Processing is local. Entered URLs are data: they are not visited, uploaded, logged or placed in the route. Generated markup is inert text. Reference lookups use bundled data, and previews are illustrative rather than guaranteed platform output.
Unknown/unassigned codes have no invented meaning. Categories cover 100–599; the reference is bundled, not live.
