  "summary": "The brief covers the importance of rate limiting for large language model (LLM) APIs, emphasizing that it is crucial for protecting both servers and bank accounts. Unlike conventional APIs, LLM API calls can be expensive, with a single request potentially costing real money, especially when an agent loop issues hundreds of them without human intervention. The article highlights the need to track tokens rather than just requests, as the latter does not accurately reflect the cost of API calls. Two windows are mentioned: a request limit for preventing runaway loops and a token limit for capping spend. The design of the limit key must contain the tenant identifier, which should come from an authenticated session, not the request body, to ensure proper security and prevent abuse.",
