SKU: E181-DFF8-56CF I have huge problems with cache calculation. For test issue I created 5 cached contents with 5 seconds time to live. All that caches was invalidated/expired after 5 seconds (which is fine). Cache check at 17 march 2026: curl -s “ https://generativelanguage.googleapis.com/v1bet…

My findings: When I first noticed this billing anomaly, the very first thing I did was use the Gemini API to FIND and DELETE all existing caches. For the last 3 days, there have been NO caches in the List whatsoever. Whenever I queried the cache list via the API, the result was completely empty. Ye…

My project has had the same issue. No increase in token usage but 20x in prices, unfortunately destroying the economics of my business. Hope this is an error not an unannounced increase

Since no one seems to care at Google, the only solution is make a tweet and tag them on X. like its crazy how a spend limit update on march 16th broke the api cost calculation, and its not the 1st time. What are you doing at this point…

You can explain anomaly to the Billing Support.

Next findinds: I am writing to share new data and findings. Here is the second reason why I am absolutely certain that a “phantom” resource was stuck on your side, and why this case needs to be reviewed by your engineering team. Currently, my Gemini API has been completely Disabled for three days (…

I also noticed this increase in costs starting on March 16, without using a cache or Google search; I wrote a post about it: URGENT: The cost of API access has increased since March 16-17, 2026
