Constant 429 for 3+ days, project quota tier unavailable (original) (raw)

January 22, 2026, 4:28am 1

Hi,

I am experiencing constant 429 errors with the Gemini API for more than 3 days, even when sending a single very small request.

Details:

Google account: <your Gmail here>
In Google AI Studio → Usage and Limits → Rate limit, I see the message:
“Project quota tier unavailable. Please contact your project administrator for assistance.”
The usage and rate limit charts show “No usage data available”, even though I am calling the API.

Example request (PowerShell):

powershell

$env:GEMINI_API_KEY = "REDACTED"

curl -Method POST `
-Uri "https://generativelanguage.googleapis.com/v1beta/models/gemini-2.5-flash:generateContent" `
-Headers @{
"Content-Type" = "application/json"
"x-goog-api-key" = $env:GEMINI_API_KEY
} `
-Body '{
"contents":[{"parts":[{"text":"Test from new key"}]}]
}'

Example response:

text

429 Too Many Requests

What I have already tried:

Waiting more than 3 days to see if the quota resets.
Creating a new API key in the same project.
Creating a new API key via Google Cloud Console.
Testing with different keys in curl (all return 429).

All keys for this account return 429 on a single short request, and the project shows Project quota tier unavailable, so it looks like a stuck quota or configuration issue on the backend.

Could you please:

Check the quota / tier configuration for project doctor-484714, and
Reset or fix the quota so that I can use the free tier (or normal tier) again?

Thank you in advance!

I’m also facing same same issue. please check google
