          :param this_hash: a md5/sha1/sha256 hash. You can also specify a CSV list made up of a combination of any of
                            the three allowed hashes (up to 25 items), this allows you to perform a batch request with
                            one single call. Note that the file must already be present in our file store.
          :param timeout: The amount of time in seconds the request should wait before timing out.
  
          :return: JSON response that contains scan_id and permalink.
