Manual billing sync request — 429 “prepayment credits are depleted” despite funded Cloud Prepay account
Hello Google team,
My project returns 429 RESOURCE_EXHAUSTED on every image generation call, with “Your prepayment credits are depleted”, even though my Cloud Prepay balance is funded and visible in AI Studio. This looks like the known billing-sync bug.
Details:
- Project name: graphics
- Project ID: gen-lang-client-03267990..
- Billing account: My Billing Account — Cloud Prepay 01175C-372731-945B..
- Tier: Paid 3 / Tier 3 · Prepay
- Credit balance shown in AI Studio: A$298.65
- Prepayment: A$300.00 added on 28 July 2026, charged successfully
- API key: single key ending jo7s, created 27 Jan 2026, confirmed to belong to this exact project
What I have already ruled out:
- The API key belongs to the correct project (confirmed on the AI Studio API Keys page — it lists project “graphics” and billing tier “My Billing Account, Tier 3 · Prepay”)
- The billing account is the same one holding the credit balance
- The balance is not zero and the payment is not pending — AI Studio’s Billing page shows A$298.65 available and the 28 July transaction recorded
Verbatim error on every call:
{
“error”: {
“code”: 429,
“message”: "Your prepayment credits are depleted. Please go to AI Studio at https://ai.studio/projects to manage your project and billing. Learn more at https://ai.google.dev/gemini-api/docs/billing#prepay. ",
“status”: “RESOURCE_EXHAUSTED”
}
}
Could a moderator please trigger a manual billing sync for this project?
Thank you.
