How this service works
Legacy alias HEAD for /site/:slug.
Output
HTTP response headers and status code only (no response body), indicating whether the slug exists, its content type, cache-control settings, and server metadata.
Example use cases
Verify published site before sharing
“Before I tweet this link, can you confirm that the withzero.ai site with slug 'product-launch' is actually up and returning a 200?”
Monitor site availability without extra data
“Ping the withzero.ai slug 'beta-invite' and tell me if it's still live — I just need the status, not the content.”
Check legacy site URL is still valid
“I have an old link using the /site/ path for slug 'team-intro' on withzero.ai — can you verify that URL still resolves correctly?”
Technical details
Endpoint
HEADhttps://site.withzero.ai/site/:slug?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify the existence or HTTP status of a withzero.ai site by slug without the overhead of downloading the full HTML body. Prefer this over GET when bandwidth is a concern or you only need header-level metadata such as status code, content-type, or cache headers.
Side effects
- 404 Not Found if the slug does not exist or has expired
- 500 Internal Server Error if the underlying storage is unavailable
- Timeout if the service is under load
- Unexpected redirect if slug has been moved to a new path
