  Lunary's API uses a sliding-window rate limiter. The current published limit is 30 requests per
  second per API key. Standard HTTP codes are returned (429 rate-limit, 422 invalid params, 403
  unauthorized, 50x server). Self-hosted deployments are unconstrained beyond your own infrastructure.
notes: Sliding window; 30 RPS per key on hosted SaaS.
