The request is refused because of the state of the account. The body is the standard error envelope with code 403, and message tells the two bodies apart.

ACCOUNT_ARCHIVED: the account was archived and its database was dropped. A request for this account is refused when it uses an API key, HMAC-signed or sent as a Bearer API-key token. A request with an OAuth access token for an archived account gets 401 instead. A cookie session is refused when every account the user holds was archived. Changing the subscription of an archived account is refused too. Support restores such an account by hand.
