  LegiScan rate limits are enforced per API key on a monthly query quota basis.
  The free Public tier is capped at 30,000 queries per month. Paid Pull
  subscription tiers provide between 100,000 and 250,000+ queries per month
  depending on the plan. Push subscriptions are not query-limited in the same
  way — updates are event-driven and delivered to the client endpoint at a
  cadence of every 15 minutes to 4 hours. The Microsoft Power Platform
  connector enforces an additional throttle of 100 calls per 60 seconds per
  connection.

  - name: Monthly quota reset
    description: >-
      Query counts reset monthly. Public keys are capped at 30,000 queries to
      mirror the OneVote public tracking service. Exceeding the quota requires
      upgrading to a paid Pull subscription.
  - name: Key-based enforcement
    description: >-
      Rate limits are enforced per API key. Each key is associated with a
      LegiScan account and its subscription tier determines the monthly limit.
  - name: Push delivery cadence
    description: >-
      Push API subscriptions deliver updates to client endpoints on a
      15-minute to 4-hour schedule as legislative changes are detected.
      There is no per-request rate limit for push delivery — the cadence is
      controlled by LegiScan's detection and delivery schedule.
  - name: Data update frequencies
    description: >-
      Individual operations have their own underlying data update frequencies:
      getSessionList updates daily; getMasterList updates hourly; getBill
      updates every 3 hours; getPerson updates weekly; getBillText,
      getAmendment, getSupplement, and getRollCall are static once published.
