I'm facing with the Gemini pro 2.5 model API 429 RESOURCE_EXHAUSTED error

Hello Google AI Developer Support,

I am writing to report a persistent issue I’m facing with the Gemini API. All my requests to the https://generativelanguage.googleapis.com/v1beta/models/gemini-2.5-pro:generateContent endpoint are failing with a 429 RESOURCE_EXHAUSTED error.

I believe this is not related to my personal usage quota for the following reasons:

  1. Error on an Inactive Key: My original API key, which I had not used for several days, started receiving this error. Given that the daily quota should have been reset, this was unexpected.

  2. Error on a Brand-New Key: To troubleshoot, I created a new API key using a completely different Google account. However, the very first request using this new key also failed with the exact same error.

Because the issue persists even on a newly generated key that has never been used, it leads me to believe this might be an internal issue within Google’s systems rather than a problem of me exceeding my request limits.

Could you please investigate the root cause of this error? I would like to understand why both my inactive and brand-new keys are being rate-limited.

Below is the full error message for your reference:

JSON

{
    "error": {
        "code": 429,
        "message": "You exceeded your current quota, please check your plan and billing details. For more information on this error, head to: https://ai.google.dev/gemini-api/docs/rate-limits.",
        "status": "RESOURCE_EXHAUSTED"
    }
}

Thank you for your time and assistance.

I concur. This has been happening to me over the past few days too. Getting 429 error when I haven’t made any requests since the previous day.

Related symptoms are:

  • Usage graphs on Google AI studio show “No Data Available” even though there have been requests made over the last few days
  • Unable to see API key “tier’ Level. It shows “Unavailable” (should say “Free”).

Yesterday I messed around trying to remove/add a billing account and creating a new project to generate a new key to try and get it working. It seems like an error on gemini’s end rather than something from the user. That has been my experience.
