Tier 1 Postpay billing account returns 429 "prepayment credits are depleted" on ALL projects — manual billing sync request

Gemini API
1

Hello, requesting a manual billing sync for the known postpay/prepay sync bug.

Symptom: Every generateContent call returns 429 RESOURCE_EXHAUSTED —
“Your prepayment credits are depleted” — even though the billing
account is active Postpay with a valid card.

Details:

  • Billing account: Inovatif360 Billing (0192F2-024EE4-312C..), active, valid card
  • Project 1: gen-lang-client-0204379997 (AI Studio shows Tier 1 · Postpay)
  • Project 2: inovatif360-gemini (created today as a clean test — same error)
  • Fresh API keys on BOTH projects tested directly via curl — same 429
  • Generative Language API enabled on both projects
  • ListModels works; only billed generateContent calls fail
  • Billing account was created today (~04:00 UTC) after KYC verification;
    error persists 18+ hours

This matches the staff-confirmed incident where accounts were erroneously
switched to prepay. Both projects affected — issue appears to be at the
billing account level. Requesting manual sync/revert. Thank you.
