there are a few examples

Also there is Retrofit adapter that allows use Deferred as return type of Retrofit interface methods https://github.com/JakeWharton/retrofit2-kotlin-coroutines-adapter Nio examples there, but you just call

await()

Not sure what you mean about “chain multiple calls”. Just call multiple requests sequentially, one by one? This is default behaviour of coroutines:

val user = api.loadUser().await()
val result = api.followUser(user..id).await()

.await()

will suspend until request result

About chaining of requests, in your last answer you have already clarified it very well
