  perMinute:
    notes: |
      Fixer / APILayer do not publish a hard per-minute throttle on the public marketplace
      listing. Consumers should expect short-window bursting and back off on HTTP 429.
  concurrency:
    notes: |
      Concurrency is not capped per request; rate caps are enforced via the monthly
      quota and the standard APILayer 429 response.
