Google Dialogflow
Google Dialogflow is Google Cloud's conversational-agent platform, shipped as two editions on one API host. Dialogflow ES (Essentials, API v2) builds intent-, entity- and context-driven agents with knowledge connectors and the Agent Assist surface for human contact-centre agents. Dialogflow CX — now branded Conversational Agents, API v3 — builds flow-based state-machine agents and generative playbook agents backed by Gemini models, data stores, generators and tool calling, with test cases, experiments, versions and environments as first-class API resources. Both are called at dialogflow.googleapis.com with a Google OAuth 2.0 bearer token; there is no API key. Google publishes no OpenAPI for Dialogflow — the first-party machine-readable contracts are the Google Discovery Documents served by the API host itself (279 operations on v2, 158 on v3) and the protobuf IDL in googleapis/googleapis (42 gRPC services, 267 RPCs).
Google Dialogflow publishes 42 API contracts indexed on the APIs.io network, including Agent API, Agents API, Answer Records API, and 39 more. Tagged areas include Agents, Artificial Intelligence, Chatbots, Conversational AI, and Google Cloud.
The Google Dialogflow catalog on APIs.io includes 1 event-driven AsyncAPI specification, 1 JSON-LD context, and 1 Spectral governance ruleset.
Google Dialogflow’s developer surface includes documentation, API reference, getting-started guide, authentication, CLI, sandbox, changelog, and 45 more developer resources.

Kin Score
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| Workplace Collaboration App Marketplaces | distribution | 9.6 (thin) | - | - |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards implemented 2
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
