our usage of gemini is very limited. using 2.5 flash or similar models. at a hackathon in bay area i used the api key in my google app script. from that day my usage overshot to insane amounts.Google started charging y card every 30 mins or so. Google support said they will help significantly waive this off but they havent been swift. any one else experienced anything similar?
痛点：LLM API key 泄露或异常调用导致账单在一天内暴涨到 2500 美元，缺乏实时预算硬上限和告警。
目标用户：使用 Gemini/OpenAI 等 LLM API 的独立开发者、黑客松参赛者和小团队
证据：My Gemini bill shot up suddenly to 2500 USD in one day. Google started charging y card every 30 mins or so. Google support said they will help significantly waive this off but they havent been swift.
变现：按项目或 API key 收费的 LLM 网关订阅，提供硬预算、速率限制、异常告警和密钥泄露检测；也可按监控调用量收费。
MVP：2 周内做一个轻量 LLM API 代理：为每个 key 设置日/月硬上限、异常调用速率告警、密钥使用来源 IP/地域限制、超额自动阻断；先支持 Gemini/OpenAI。
竞品：Helicone、Portkey、LiteLLM、OpenRouter、云厂商预算告警
摘要：HN Ask 帖称 Gemini 用量有限却在一天内账单飙到 2500 美元，疑似黑客松暴露 API key 后遭滥用，Google 每 30 分钟扣款且支持处理缓慢。帖子仅 5 分 0 评论，属于单一案例，但暴露了 LLM API 预算硬上限与密钥泄露防护的真实痛点。
