Free Tier Quota Locked at 0 on Brand New Project (Error 429) - Need Manual Review

Hello everyone,

I am currently developing an application to process and extract data from extensive legal documents, and I’m trying to use the Gemini 2.0 Flash model via the AI Studio API for its large context window. However, my account seems to be stuck in an automated quota lock, and I cannot use the Free Tier at all.

Whenever I make a request, I immediately get a 429 Resource Exhausted error stating my limit is exactly 0.

The Error:

JSON

"quotaMetric": "generativelanguage.googleapis.com/generate_content_free_tier_requests",
"quotaId": "GenerateRequestsPerDayPerProjectPerModel-FreeTier",
"quotaDimensions": {
  "model": "gemini-2.0-flash",
  "location": "global"
},
"limit": 0

Troubleshooting Steps I’ve Already Taken:

  1. I created a completely brand-new, clean project specifically for this (named “Radar perito LIMPO”).

  2. I ensured that no billing account is linked to this new project.

  3. I generated a fresh API key from Google AI Studio tied exclusively to this clean project.

  4. I tested the key using an isolated Python script to rule out caching issues in my application.

Despite this, the API still returns the limit: 0 error. Furthermore, on the AI Studio API Keys page, this new project is listed with the status Nível 1 - Pós-pagamento (Tier 1 - Post-payment) asking to “Configure prepayment”, even though I never enabled billing for it.

It appears my Google account has been flagged by an automated system, completely revoking my Free Tier access.

Could a moderator please take a look at my account/project and help restore the Free Tier quota?

My Details:

  • Project ID: [Insira aqui o ID do seu projeto limpo, ex: radar-perito-limpo-1…]

  • Model: gemini-2.0-flash

  • Region: Brazil

Thank you in advance for your help!

UPDATING:

I tried creating a completely new Google account and the exact same limit: 0 error occurred instantly. It seems my IP or environment has been flagged by the automated anti-abuse system.

Hi

You are trying to access Gemini 2.0 Flash - this model has been deprecated https://ai.google.dev/gemini-api/docs/deprecations#gemini-2.0-models

Can you trying testing with the latest models ?

Yes, I’ve already tested it with the new versions, and it had the same issue.
