Request body

hostsstring[] required

Distinct hostname patterns to append. Provide hostnames only, without scheme, port, path, userinfo, query, or fragment. *.example.com matches one subdomain label; **.example.com matches one or more. Neither includes the apex. Patterns are canonicalized before comparison.

Response

Response for status 200

hostsstring[] required

Canonicalized hostname patterns trusted to embed previews. Exact hosts match only themselves; *.example.com matches exactly one subdomain label; **.example.com matches one or more subdomain labels. Wildcards do not include the apex, so list example.com separately when it should also be trusted.
