Google Dialogflow Plans Pricing
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.
