Google cloud vision api is very powerful and now they have support for pdf format, but the documentation is getting me confused, can someone pls guide a noob how to set up and process a pdf file using vision api.
kind of like starter tutorial
ref: https://cloud.google.com/vision/docs/pdf#vision-web-detection-gcs-protocol
The confusion is how to pass the command arguments, and send my sample file and retrieve the results in csv or json format
Should i use my windows command line or cloudshell on google cloud
There is good starter reference for other services , if you look at this https://cloud.google.com/vision/docs/ocr#vision-detect-labels-gcloud, they have clearly given commands to use in different envs

You could use the following curl command as a base and run it within your Google Cloud Shell session:
curl -H "Authorization: Bearer "$(gcloud auth application-default print-access-token) --header "Content-Type: application/json" --request POST --data '{ "requests":[ {"inputConfig": { "gcsSource": { "uri": "gs://<Your Bucket>/<Your PDF FIle>"},"mimeType":"application/pdf"},"features": [{"type":"DOCUMENT_TEXT_DETECTION"}],"outputConfig": {"gcsDestination":{"uri": "gs://<Your destination bucket/"},"batchSize": 2}}]}' https://vision.googleapis.com/v1/files:asyncBatchAnnotate
Then, you'll get an operation object as a response like this: "name": "operations/<This is your operation ID>".
After that, you'll get your results with the GET request, for instance:
curl --request GET https://vision.googleapis.com/v1/operations/<The Operation ID>?key=<Your API Key>
