This is an emacs library of Google Cloud API routines. They are generated using Googles' discovery documents.

It basically is just a library of functions for accessing google-cloud api endpoints. For example, I'm learning French and I use Google's text to speech interface to translate French text into audio like this:
(defvar my-api-key "<my-api-key>")
(defvar my-response nil)
(defvar my-bytes nil)
(defun my-save-speech (text outputfile)
(setq my-response (google-texttospeech-v1:text/synthesize
nil
`((key . ,my-api-key))
`((input . ((text . ,text)))
(voice . ((languageCode . "fr-CA")
(name . "fr-CA-Wavenet-B")))
(audioConfig . ((audioEncoding . "OGG_OPUS"))))))
(setq my-bytes (base64-decode-string (cdr (assoc 'audioContent my-response))))
(with-current-buffer (find-file-literally outputfile)
(erase-buffer)
(insert my-bytes)
(basic-save-buffer nil)
(kill-buffer)))
(my-save-speech "bonjour parlez-vous française garçon?" "/tmp/speech.opus")
