Zones

GET/zonesList zones

Returns all DNS zones accessible to the authenticated identity.

Path & query parameters

Name	Type	Required	Description
`zoneName`	`string`	-	Exact zone-name filter. Returns { zones: [...] } with just that zone (or an empty list). Single-label-safe, unlike suffix_of. "name" is an accepted alias.
`name`	`string`	-	Alias for zoneName.
`suffix_of`	`string`	-	Longest enclosing-zone match for a FQDN (cert / delegation-parent lookup). Returns a single Zone object, or 404 if none. Requires >= 2 labels, so it does NOT match single-label names - use zoneName for those.

curl -X GET https://api.yeil.app/v1/dns/zones \
  -H "Authorization: Bearer $YEIL_API_KEY"

Responses

200Default and with zoneName/name: { zones: [...] }. With suffix_of: a single Zone object.

POST/zonesCreate a zone

Registers a new DNS zone. Returns the zone and a status indicating whether DNSSEC DS delegation or a Handshake claim is required.

Request body

Name	Type	Required	Description
`zoneName`	`string`	required	The zone apex domain name (e.g. example.com).
`owner`	`string`	-	Zone owner. Use "org:<teamId>" to create in a team, or "personal" (the default when omitted) for a personal zone. App-account keys (yk_) MUST set this to "org:<their own teamId>" and that team must match the key's team - app keys cannot create personal zones, and a missing or bare-id owner is rejected with 403 "app can only create zones in its own team". The key also needs manage-zones = write.

curl -X POST https://api.yeil.app/v1/dns/zones \
  -H "Authorization: Bearer $YEIL_API_KEY"

Responses

200On status=done the response carries id + nameservers + ds so a client can wire records/DS in one call (no follow-up GET to recover the id).
