Polyai

PolyAI builds enterprise-grade voice and chat AI agents that handle real customer service conversations across 24+ languages, with 99.994% production uptime. The PolyAI Platform exposes three REST API families — an Agents API to create, branch, configure and deploy agents through environments; a Conversations API to retrieve transcripts, audio, metrics and session data; and a Webhooks & Alerts surface for real-time event notifications — plus Chat, SMS, Outbound Calling, Handoff, DNI, External Events, Messaging (WebSocket) and a WebRTC Gateway. Authentication is header-based (x-api-key) with region-scoped keys, and a Python Agent Development Kit (ADK) offers a Git-like local build-pull-push workflow. Backed by Khosla Ventures and profiled in the API Evangelist network.

Polyai publishes 1 API on the APIs.io network. Tagged areas include Company, Conversational AI, Voice AI, Customer Service, and Contact Center.
