  Dialogflow / Conversational Agents pricing, read from Google's own pricing page on 2026-09-12.
  This replaces a 2026-05-04 scaffold whose Free/Professional/Enterprise tiers and TBD prices were
  placeholder defaults that matched nothing Google publishes. Dialogflow does not sell subscription
  tiers: it is pure pay-as-you-go usage billing on a Google Cloud account, priced per request for
  chat agents and per second of audio for voice agents. The only tier-shaped distinction is the ES
  Trial vs Essentials edition split, which is a quota and SLA boundary rather than a price list.

  dialogflow_es_trial_edition:
    price: '0.00'
    note: >-
      Dialogflow ES has a free Trial Edition with reduced quotas (180 text rpm, 1000 audio
      requests/day) and no SLA coverage, versus the paid Essentials Edition. See
      rate-limits/google-dialogflow-rate-limits.yml.
billing_definitions:
  turn: A single interaction within a conversation — one user input paired with one agent response.
  request: Any API call to the platform, direct via the API or indirect via an integration or the
    console.
  session: A conversation between an end user and an agent; chat sessions use text, voice sessions
    use audio.
hybrid_billing:
  note: >-
    Billing aggregates per turn and each turn is billed by the features it consumed. If a Flow calls
    a Playbook, only the Playbook turns are billed at the Playbook rate. If a Playbook calls a Flow,
    the ENTIRE conversation is billed at the Playbook rate — a material asymmetry for anyone costing
    a hybrid agent.
