Relay

Realtime video & voice, in minutes.

Relay puts you in control of realtime video and voice. Mint access tokens from one simple API and let your users talk instantly, on standard LiveKit clients, with no lock in.

Get started

Add video in 5 minutes

Mint a token from your server, hand it to a LiveKit client — that's it.

  1. 1
    Request a token

    POST to /v1/tokens with a room and identity from your server.

  2. 2
    Get back a token + URL

    Relay mints a scoped LiveKit access token and returns the connection URL.

  3. 3
    Join with any LiveKit SDK

    Pass token and url straight into the client SDK to connect.

Request
curl -X POST https://api.relay.welbuiltai.tech/v1/tokens \
  -H "Authorization: Bearer sk_live_your_key" \
  -H "Content-Type: application/json" \
  -d '{"room":"my-room","identity":"user-123"}'
Response
{
  "token": "eyJhbGciOi...",
  "url": "wss://relay.welbuiltai.tech",
  "room": "my-room"
}

Everything you need to ship realtime

A thin, predictable gateway in front of LiveKit.

Per-project isolation
Tokens are scoped to your project and rooms are auto-namespaced, so projects never collide.
Usage metering
Track participant-minutes in real time and see your savings versus Twilio at a glance.
No client lock-in
Join with the standard LiveKit client SDKs. Relay only mints tokens — the media path is pure LiveKit.
