+## Cloud Scheduler for Daglig Fakturering
+For å automatisk generere daglige kostnads-snapshots, må en Cloud Scheduler-jobb konfigureres til å kalle `/billing/snapshot`-endepunktet.
+
+**Oppsett med `gcloud`:**
+1.  **Service URL:** `https://osvauco-agent-357036551735.us-central1.run.app`
+2.  **Service Account:** `osvauco-agent-sa@propane-will-491900-m5.iam.gserviceaccount.com`
+
+```bash
+gcloud scheduler jobs create http daily-billing-snapshot \
+  --schedule="0 5 * * *" \
+  --uri="https://osvauco-agent-357036551735.us-central1.run.app/billing/snapshot" \
+  --http-method=POST \
+  --oidc-service-account-email="osvauco-agent-sa@propane-will-491900-m5.iam.gserviceaccount.com" \
+  --oidc-token-audience="https://osvauco-agent-357036551735.us-central1.run.app" \
+  --location="us-central1" \
+  --time-zone="Etc/UTC" \
+  --description="Kaller /billing/snapshot for å lagre daglig kostnadsdata."
+```
+Denne kommandoen oppretter en jobb som kjører hver dag kl. 05:00 UTC.
