Using HttpApi to Model and Validate External APIs

const ExternalAPI = HttpApi.make("ExternalAPI").add(
  HttpApiGroup.make("someGroup").add(
    HttpApiEndpoint.get("someEndpoint")`/`.addSuccess(Schema.String)
  )
)
// Implement the "Greetings" group
const GreetingsLive = HttpApiBuilder.group(ExternalAPI, "someGroup", (handlers) =>
  handlers.handle("someEndpoint", () => Effect.gen(function* () {
    // use a http client to call the actual third party API
  })
)

const client = yield* HttpApiClient.make(ExternalAPI, {
    baseUrl: "https://external-api"
  })
