6Sense Insights Rate Limits

6sense publishes a single flat rate limit that applies across its REST APIs, stated in prose on the API reference. It publishes NO rate-limit response headers — there is no X-RateLimit-*, RateLimit-* or Retry-After documented anywhere, so an agent cannot read remaining budget or a reset time from a response and can only detect exhaustion after the fact from a 429. That is the operationally significant finding here, not the number.
