About tapir
Tapir is a Scala library that lets developers describe an HTTP API once in a type safe, declarative form and then expose that description as a server, consume it as a client, and generate OpenAPI, AsyncAPI, and JSON Schema documentation from it, and it is aimed at Scala teams building HTTP services that want their API documentation to stay in step with their code.
