  Rate limit posture for the Ketch Platform API at global.ketchapi.com. Ketch does not publish a
  fine-grained public rate limit schedule; the plan-level limit that drives metering is the monthly
  unique-user count (5k Free, 30k Starter, 100k Plus, custom Pro/Enterprise). Server-side API calls
  are governed by Harbormaster auth and standard abuse protections.

    notes: |
      Ketch does not publish per-key request-per-minute limits. Consent collection from the Web/iOS/
      Android SDKs is gated by the plan's monthly unique-user allowance rather than per-second RPS
      quotas. Excess traffic is renegotiated with sales rather than 429'd.
