Checklist

• Add adapter modules under lib/app/adapter and keep parsing logic in dedicated submodules if needed.
• Use Req.new/1 to build a context (base URL, headers, auth) and Req.get!/post!/patch! for calls.
• Return {:ok, value} or {:error, reason} consistently; avoid throwing in callers.
• Read secrets and host config from config/*.exs or runtime.exs.
• Never use other HTTP clients (:httpoison, :tesla, :httpc).
