Billing account ID: 012C74-AD826B-567E..
Project: My First Project (pivotal-pattern-1438,)
Plan: Tier 1 · Prepay
Credit balance: ₪95.53 (₪100 added 2026-07-28, shown settled in the AI Studio console)
Since the top-up, generateContent has continuously returned 429 RESOURCE_EXHAUSTED “Your prepayment credits are depleted. Please go to AI Studio at https://ai.studio/projects to manage your project and billing.” (2+ hours and counting). The balance is funded and the console shows no outstanding payment problem.
Same API key, same project, three endpoints side by side:
models.list -> 200 OK
countTokens -> 200 OK
generateContent -> 429 "prepayment credits are depleted"
Only the metered endpoint is blocked, so the key, project and auth are all valid.
This matches the serving-layer / billing-ledger desync reported in several other recent threads on this forum. Requesting a manual billing sync on this billing account. Happy to provide any further details.
