Look up a status, pick the right one for an API, or hit a live endpoint that actually returns it. Add ?code=418 to this URL and the response is that status — useful for curl, interceptors, and “what does my client do on 503?” Nothing here phones home except the Try it fetch to this same page.
Which class?
Permanent new URI; method and body must be reused. Safer than 301 for APIs.
When to use
API path relocations, HTTPS upgrades when you need to keep POST.
Don’t
HTML sites that want crawlers to GET the new URL often still use 301.
Live URL
curl -i https://corecoding.com/utilities/http-status.php?code=308
No codes match.
