Test services

Something to point Sendwire at while you learn it, or while you test Sendwire itself. Sendwire runs a small public API under *.sendwire.dev — an HTTP echo, a raw TCP/TLS endpoint, a WebSocket echo, a SOAP service and a GraphQL API.

They exist to exercise the parts of the app the exchange view is for: timing waterfalls, streaming, WebSocket frames, the certificate chain, WSDL import, and GraphQL introspection.

Host	For
echo.sendwire.dev	HTTP echo — tells you exactly what arrived, plus /mirror, /delay, /status, /stream and /sse.
socket.sendwire.dev	The same service for raw TCP and TLS.
ws.sendwire.dev	A WebSocket echo — every frame comes straight back.
soap.sendwire.dev	A SOAP 1.1 service with a WSDL.
graph.sendwire.dev	A simulated GraphQL API.

The reference

https://api.sendwire.dev documents every host and endpoint — the echo response shape, the streaming and SSE paths, the SOAP operations and the GraphQL schema — with copy-paste examples. The REST echo answers there under /rest (for example https://api.sendwire.dev/rest/get).

Every host, endpoint and limit is also published as data at https://echo.sendwire.dev/services.json — the service itself is the copy that is always right.
