WebTransport
A bidirectional, low-latency transport-layer protocol built on HTTP/3. It supports establishing UDP-like datagram streams and bidirectional tunnels within a single HTTP connection and is commonly used in real-time applications and agent protocol stacks.
Timeline (last 90 days)
The x402 protocol ecosystem has launched two new paid APIs: a WebTransport probe endpoint and a DID resolution catalog endpoint.
The /api/webtransport-probe endpoint performs 8 HTTP/3-based WebTransport capability audits on a target URL.
Extended CONNECT carries the :protocol pseudo-header (RFC 8441, RFC 9221) and can establish bidirectional WebSocket or WebTransport tunnels; :protocol=connect-udp indicates a datagram stream carrying UDP semantics over HTTP/3.
