Gemini API Grounding - Billing for requests exceeding daily free tier

Hi Google team,

I need clarification on how billing works for Gemini API grounding with Google Search when exceeding the 1,500 free daily requests.

The pricing shows $35/1,000 requests, but I need to understand:

  • If I use 1,510 requests (10 over the free tier), am I charged $0.35 (proportional) or the full $35 (minimum billing unit)?
  • How exactly are grounding requests counted and billed?

Could someone from the Google team please clarify the exact billing methodology?

Hi @Nishita_Vaid,

For Gemini API grounding with Google Search, there’s a daily free tier of 1,500 requests. After exceeding this, the cost is $35 per 1,000 requests. If you make 1,510 requests, the extra 10 requests will be charged proportionally, amounting to $0.35.

Each API call using the google_search tool counts as a single billable grounding request, even if multiple search queries are performed for one response.

Thank you!
