How it works

Links are extracted from the href attributes you paste, then de-duplicated and checked one by one.
Checks use a free public header API with a shared daily allowance, so the run is capped — start with the most important links.
Links that start with / are resolved against the base URL above; without a base they are reported as skipped.
Fragments, mailto: and tel: links are skipped because they cannot be requested over HTTP.
