📡 HTTP Status Codes & Headers

Browse every standard HTTP status code and a curated set of common request/response headers, filter to find one fast, and click any code or header name to copy it.

How to Use This Reference

Switch between Status Codes and Headers with the toggle above, then filter or scroll to find what you need. Click (or focus and press Enter on) any code or header name to copy it to your clipboard.

Handy for picking the right status code for an API response, remembering what a header actually does, or double-checking a code you just got back from someone else's API.
