Every operation of the Sending and Team APIs, keyed by "<METHOD> <path>".

Each entry is a map with these keys:

• :operation_id, :summary, :method (an atom such as :get) and :path
• :auth: :sending, :team or :either, by the tokens the operation accepts
• :surfaces, :path_params, :headers
• :query: the query type module, or nil
• :request: %{type: module, content_type: String.t(), required: boolean()} or nil

• :response: %{status: [integer()], content_type: String.t() | nil, type: module | :text | :empty}

• :errors: each error status with the type modules its body may have (:text for a text body)

• :pagination: %{items: module, cursor_param: String.t(), size_param: String.t() | nil} or nil

• :deprecated

The table is data, not a client: the SDK's functions read it.
