I’ve just had an emall advising me that a payment has been declined on my Google Cloud account. This came as news to me, as I was not aware that I was using any chargeable services. When I explored my account (at https://console.cloud.google.com/billing) it showed that the charge related to a project that I had created last December in order to enable Gmail integration in HA. The charge was £0.01259 for May 30th, and seems to be related to the Gemini service (SKU: Generate content input token count gemini 2.5 flash short input text), but there was no indication of what the ongoing charges might be.
Does anyone know why/if this type of project attracts charges from Google?
