    Published by the API about itself: GET /api/v1/catalog/health returns
    "rateLimit": "best-effort 20 requests per minute per Cloudflare isolate".
    "Best-effort" and "per isolate" are the provider's own words and matter — the ceiling is
    enforced inside a single Cloudflare Worker isolate rather than globally, so the effective
    limit a caller sees varies with edge placement and is neither a guarantee nor a quota.
  observability: >-
    No RateLimit-*, X-RateLimit-* or Retry-After headers were returned on any probed response
    (200, 400, 405, 413, 415). A client cannot read remaining budget; it can only observe a 429
    after the fact and back off blindly.
bounds:
  note: >-
    Request-size bounds do more limiting work here than the request-rate limit does.
