  LegiScan is a national legislative tracking service providing real-time data
  on bill activity, voting records, and legislative actions across all 50 US
  states and Congress. The LegiScan API offers a JSON-based RPC-style interface
  supporting both pull and push data delivery models. Developers and
  organizations can monitor legislation in near real-time, search full-text bill
  content, retrieve roll call votes, access sponsor and legislator information,
  and download bulk session datasets. The free public tier provides 30,000
  queries per month, with paid subscription plans offering higher limits and
  push-based real-time updates pushed every 15 minutes to 4 hours as changes
  are detected.

      The LegiScan Pull API is an RPC-style JSON service that allows clients to
      query the national legislative database on demand. Operations include
      retrieving session lists, master bill lists, bill details, full bill text,
      amendments, supplements, roll call votes, person/sponsor information, and
      full-text search across all 50 states and Congress. Authentication uses an
      API key passed as a query parameter. The free public tier supports 30,000
      queries per month; paid subscription tiers provide higher query limits.

    description: >-
      The LegiScan Push API is a paid subscription service that delivers
      real-time legislative updates to a client-hosted endpoint. Changes
      detected in bill information are pushed every 15 minutes to 4 hours
      depending on subscription tier and coverage (single state to full
      national). Clients implement a push endpoint listener that validates
      incoming payloads via an Authorization header using the api_auth_key.
