Status	Code	Meaning
400	`invalid_request`	The request is malformed: bad JSON, an unknown or invalid field, or a missing header.
401	`invalid_signature`	The MK-* headers are missing or malformed, the key id is unknown, or the signature doesn't match.
401	`key_expired`	The key has passed its expiry date.
401	`key_revoked`	The key was revoked.
401	`timestamp_out_of_range`	MK-Timestamp is more than 30 seconds from the server clock.
401	`nonce_reused`	This key already used this MK-Nonce.
403	`ip_not_allowed`	The request came from an address outside the key's IP allowlist.
403	`insufficient_scope`	The key doesn't have the scope this endpoint needs.
403	`account_restricted`	The account can't use the API right now (for example locked, inactive, or onboarding not finished).
403	`api_access_disabled`	API access is switched off.
429	`rate_limited`	Too many requests. Wait for Retry-After seconds.
