~500$ in unauthorized Gemini API charges from a Vite-built client bundle — requesting billing review

Hi,

I am reporting a billing issue with the Gemini API.

On May 30–31, 2026, my project AgoraStoryVerse v1 (gen-lang-client-01329639.., projects/6118056588..) exceeded the monthly spending limit I had explicitly set at €600. Despite this limit, the usage continued and reached €1,006.55.

A hard spending limit is expected to prevent this kind of overrun. My billing page now shows an outstanding balance of €787.01, including a sudden spike of €409.29 on May 30–31.

This appears to be the same type of issue already reported by other users, including the the $2,200 case from April 20–22, the $4,368 case from April 27, and ~$6,000 in unauthorized Gemini API charges from a Vite-built client bundle — requesting billing review .

I am requesting a review of this incident, and if possible an explanation of why the spending limit failed to stop usage, and a billing adjustment/refund/credits for the charges above the €600 limit.

Screenshots are attached.

Btw: I love your products, and I hope we can resolve this issue rapidly.

Thanks in advance for your help.

Hi @David_Langle ,

There can be a small delay before the spend cap kicks in, so if the overage of ~$400 happened in the space of a few minutes, that’s likely the reason.

If that’s not the case, please let us know & we can look at next steps.
