Token Budget Alarm on a Free Server
A free model quota is a budget, not a gift. You should treat it like one if you plan to build anything on top of it. I learned this the hard way when my prototype stopped responding in the middle of a demo. I had silently burned through the monthly allowance, and the provider cut me off without warning. This article shows how I built a small token budget alarm on a free server. It watches a free…
A free model quota is a budget, not a gift. The provider cuts off access without warning when the allowance is exhausted. This article demonstrates how to create a token budget alarm on a free server to monitor usage and alert before the budget runs out. Most developers track cloud spend but neglect model token consumption. The free tier often feels like a gift, leading to unexpected cutoffs.
A token budget alarm prevents this uncertainty by measuring actual usage and projecting the exhaustion date. The solution consists of a simple Flask application acting as a reverse proxy in front of the model endpoint. It records token usage from each response and stores it in a local SQLite database. A background thread calculates average consumption over a sliding window and compares it to the remaining allowance.
If the projection indicates the allowance will be exhausted within 24 hours, it sends a webhook alert. The proxy is lightweight and can run on a free server, such as MonkeyCode s free server option. The code extracts the token count from each response, dividing the character count by four as a rough estimate if no usage object is provided.
Every request is accounted for, as a single long prompt may consume more tokens than multiple smaller ones.
