Reactor

Reactor is a real-time video AI platform that streams generative video from GPU-hosted models to web and mobile applications over WebRTC, with sub-second round-trip latency and no infrastructure to manage. Developers connect through a JavaScript/React SDK or an async Python SDK, mint short-lived session tokens from a long-lived account API key, and control generation with a command/event channel (set_prompt, start, pause, reset). Its model catalog includes Helios (interactive real-time generation), SANA-Streaming (video-to-video editing), LingBot and LingBot World 2 (navigable worlds), X2, LongLive-2.0 and HappyOyster. Reactor is backed by Amplify Partners and Lightspeed Venture Partners and is currently in public beta.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Reactor

Each block below is one kind of artifact we hold for Reactor. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

APIs 1

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Individual APIs this provider publishes, each with its own machine-readable definition.

Reactor Realtime Video API

Real-time generative video platform. A REST token endpoint mints session-scoped JWTs; a WebRTC data channel carries the command/event interface that controls model generation an...

MCP Servers 1

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

Event Specifications 1

Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

Reactor Helios Realtime API

Real-time video generation control channel for Reactor's Helios model, exchanged over a WebRTC data channel after a session reaches "ready". Clients send commands; the model emi...

Security Posture 2

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
