notes:
  - Limits are enforced per organization, not per API key or user.
  - HTTP 429 (Too Many Requests) is returned when the per-minute rate limit is exceeded.
  - The API supports 8 datacenter domains (.com, .eu, .in, .com.au, .jp, .ca, .com.cn, .sa); rate limits apply independently per datacenter.
  - OAuth 2.0 tokens are used for authentication; token generation calls may count toward limits.
