I'm having trouble with Glide Query API usage

On Saturday afternoon, my account was migrated from the Legacy Business plan to the new Glide pricing model.

Before the migration was completed, I made sure to disable all actions using Trigger Webhook and Files Update, since those would generate extra updates under the new pricing.
My goal was to keep the app using only Glide Tables and Big Tables, which, according to the plan details, shouldn’t generate additional updates.

However, I’m now being charged for something called “Glide Query API”, and the number of updates increased very quickly — from Saturday until now, my usage has already reached 3,697 updates, which is far higher than I expected and wasn’t something I was charged for under the Legacy plan.

The only API usage I have is a single GET Rows request from one specific glide big table with 32k rows, used to power a Streamlit dashboard in Python.
This request is not scheduled, it only runs when someone opens the report manually. So on Saturday afternoon, when no one on my team was working, there shouldn’t have been any activity — yet I saw over 2,000 updates being consumed gradually.

I’m currently in contact with support to have my API key blocked while investigating the issue, since I see three possible scenarios:

  1. Something changed in the API billing policy during the transition, and I’m now being charged differently for the same usage;

  2. Someone might be using my API key without authorization;

  3. Something may have gone wrong in the Enterprise migration, causing these charges by mistake.

Has anyone experienced something similar, or used the API in a setup with Streamlit or similar tools?
I’d really appreciate any insights to help me understand if I might be misinterpreting how API usage is counted, since I haven’t changed anything about how my app interacts with the API compared to before the new pricing model.

Previus usage between September 15th and October 11th (Bussiness Legacy Plan)

Current usage between Saturday, October 11th until now (Enterprise Plan)
