Billing & Cloud Vision API issue with "Recognize Text" on Android system

[IanWu]

Hi there,

Here I got a billing problem with Cloud Vision API.

First, I follow this link to setup my Firebase project to enable the feature of "Recognize Text".

https://firebase.google.com/docs/ml/android/recognize-text

Then all the functions used are normal. I call the function of "annotateImage" in Cloud Functions to invoke the Cloud Vision API, then can also used successful.

Absolutely, I have trace the flow and requests on Cloud Vision API, it is just looks reasonable.But the issue I encountered is, "it still charges when I'm not using it", also when it has no any flow and requests! 

Billing, September 1-22, 2022 (the project has billing alerts set up now) :

Cloud Vision API, 30 days to 9/22/2022 :

It would be so gratefull if there any good suggestions !
