Developer Quickstart

Start streaming in under 3 minutes

1

Generate your API Key

Create a scoped key in the developer console with streams:write permissions.

strm_live_9a2f7c0018b3e944d187
2

Create an Ingest Session

Call the /v1/streams endpoint. It returns an isolated RTMP ingestion endpoint and active stream key.

3

Syndicate Everywhere

Attach destination channels (Twitch, YouTube, Kick, Facebook) and call /v1/broadcasts/start.

Built for High-Scale Live Video

Everything you need to orchestrate live video ingest, transcoding, and syndication at programmatic scale.

RTMP Ingestion & Transcoding

Sub-second global RTMP, SRT, and WHIP (WebRTC) ingestion. Our edge infrastructure transcodes your stream into adaptive multi-bitrate ladders with zero additional CPU overhead on the broadcaster side.

  • Hardware NVENC & QuickSync edge pipelines
  • Sub-300ms glass-to-glass replication delay

Webhooks & Real-time Events

Keep your backend in sync with guaranteed webhook delivery. Receive alerts for stream connection, degradation, resolution changes, viewer milestones, and graceful disconnections.

  • HMAC-SHA256 signature verification headers
  • Automated exponential backoff retries over 24h

Studio Embed SDK

Embed our WebRTC broadcast studio directly inside your SaaS, community platform, or mobile app with our lightweight JavaScript and React component wrappers.

  • Custom branding, white-label overlays, & layouts
  • Participant invite links & pre-broadcast greenrooms

Real-time Analytics API

Poll or subscribe via WebSocket to per-second telemetry data: bitrate variance, audio clipping, dropped frames, concurrent viewers by platform, and geographic viewer breakdown.

  • Aggregated audience totals across all destinations
  • Automated QoE (Quality of Experience) health scores
