CSV import via Google Cloud Billing. Gemini API and Vertex AI spend lives in your GCP billing account. Export it from the Billing reports page. Infrastructure billing only; no access to your data or prompts.
Whereconsole.cloud.google.com → Billing → Reports
Steps
Open Google Cloud console → Billing → Reports (you need Billing Account Viewer).
Group by Date, then filter Services to “Gemini API” (and “Vertex AI” if you use it).
Download CSV from the control above the summary table.
In Ratelytics, open Connections → Import CSV, choose the “Google Cloud billing CSV (Gemini)” preset and upload.
Good to know
Free-tier Gemini usage produces no billing rows. Only paid usage appears.
A live connector (service-account JSON reading the BigQuery billing export) is planned; the export path above needs no service account at all.
