  No published rate limits, because no public API is documented. The one API host on the domain,
  data.21shares.com (an AWS API Gateway behind CloudFront and Cloudflare), returns 403
  {"message":"Forbidden"} to every anonymous request and emits no RateLimit-*, X-RateLimit-* or
  Retry-After header, so nothing could be observed at runtime either.
