insufficient_scope
HTTP 403. The key is valid but does not carry the scope this endpoint requires. The endpoint’s required scope is listed on its reference page.
What to do: Create a key that includes the required scope. Scopes are fixed at creation - they cannot be added to an existing key.
Every error is an RFC 9457 problem document - match on code
(stable forever), show detail to humans, and quote instance when reporting an
occurrence to support.
