  No published rate limits. 4G Clinical has no developer portal or API reference in which
  limits could be documented, and the live API host cannot be observed anonymously:
  https://api.4gclinical.com returns HTTP 403 (AWS API Gateway ForbiddenException) to every
  path, with no RateLimit-*, X-RateLimit-* or Retry-After header on the response. Any limits
  that exist are settled inside a sponsor integration agreement. An honest zero.
