Authentication
This endpoint is public. It takes no credential and no organisation — it is what our own marketing site and AI answer engines read.
This endpoint takes no organisation id. Your key already identifies the organisation it belongs to, and the response is scoped to it.
Try it
Replace anything in angle brackets with your own values, and the key placeholder with a key from your dashboard.
curl -X GET https://api.zinndigital.com/v1/public/domain-holder/ask?domain=<domain>Signed in? The API console in your dashboard fills in your real organisation id and your own key, and runs the request against the live API so you can see the actual response. Open this endpoint in the API console
Details
The ask endpoint of the domain holder-page edge's on-demand TLS (docs/845). Answers 200 only for a domain we hold a DNS zone for, with no site attached and not deleted, at its apex or www; 404 for every other hostname. This is what stops the edge requesting certificates for arbitrary names that point at it. Deliberately not a delegation check: a parked domain pointed away and back shows its page again with no action. Unauthenticated and answered from our own rows only.
