  Arthur publishes a single flat throttle for the whole API - 5,000 requests per hour,
  described as a worldwide limit - and invites accounts that need more to contact technical
  support. No per-endpoint, per-plan or per-token limits are published, and no rate-limit
  response headers or throttling status code are documented.
