## TL;DR

WebRTC is a browser API family for real-time audio, video, and data communication. The public article is now limited to the W3C standard and MDN API references for the core transport and peer-connection claims.

## Evidence Notes

- W3C defines the WebRTC browser API surface.
- MDN summarizes the peer-to-peer media and data use case.
- MDN's RTCPeerConnection reference anchors the connection-object claim.
