A developer experienced an unexpected AI cost of nearly $27 in one day due to an inefficient LLM polling setup. The issue arose when a scheduled task, intended to check an inbox every three minutes, made full model calls. When the free model began returning rate limit errors, the system's fallback mechanism switched to a paid model without any cost monitoring, leading to the high bill. To prevent recurrence, a 40-line Python script was developed to monitor API spending via OpenRouter's usage endpoint, triggering alerts when costs exceed predefined thresholds. AI
