OpenAPI 3.0 docs for all Wire APIs

This wire-server system provides OpenAPI 3.0 documentation of our HTTP REST API.

The openapi docs are correct by construction (compiled from the server code), and more or less complete.

Some endpoints are version-controlled. Show all supported versions. find out more.

Public (all available versions)

Internal (not versioned)

Openapi docs for internal endpoints are served per service. I.e. there's one for `brig`, one for `cannon`, etc.. This is because Openapi doesn't play well with multiple actions having the same combination of HTTP method and URL path.

Federated API (backend-to-backend)
