Create domains

POST /v1/platform/projects/{project}/apps/{app}/domains

Attaches a hostname — instantly if you already own it, otherwise with a DNS challenge.

It attaches host to the app, and which of two things happens depends on who owns the name. A host inside the caller org's own subtree is structurally owned, so it goes ACTIVE immediately and answers 201. A bring-your-own host is claimed as PENDING and answers the DNS challenge records to publish; it is NOT rendered into the app's ingress until /verify passes.

Claims are globally unique. A host already claimed by another organization is 409, and so is one claimed by a different app in your own; re-adding this app's OWN claim is idempotent and answers its current state at 200. The default host is always attached and re-adding it is 409. A host under the platform's shared apex that is not the caller's own subtree is 403 — it belongs to whoever owns that subtree and can never be grabbed through the custom path.

host must be a valid DNS hostname; anything else is 400. Requires a validated principal; 401 without one.

Request

5 fields, body application/json (required).

Response

200 body — 12 fields.

Failure carries the platform error shape — see Errors.
