      200 requests per minute per host. Real-Time API data is cached and only
      updated every 3 seconds, so polling more frequently than every 3 seconds
      returns identical data and wastes quota.

notes:
  - Real-Time API query results are cached for 3 seconds; align polling to that
    cadence.
  - Historical (Advanced Queries) results recommend no more than 10,000 rows per
    query via the limit= parameter.
