429 quota exceeded

[Arthur_Safar]

. I am building a book to TTS platform.

I am already hitting 429 error quota exceeded while testing even though i am nowhere near the gemini-2.5-flash-tts quota levels. I have tried both Cloud API and Vertex AI, different region (global, US) endpoints. I have been having this issue a lot past 2-3 weeks

I am hitting 429 error quota just for 10-15 requests per minute.

I am on Paid tier, Pay as you go with billing enabled.

Here is the error.

[TTS] Stack trace: Error: Cloud TTS API error 429: {
“error”: {
“code”: 429,

“status”: “RESOURCE_EXHAUSTED”
}
}

I am getting the same error. It was that you are exceeding the amount of queries. You will need to try and request additional quota but I have not been able to succeed at doing it.

Any help?
