Your goal is to limit each client application to a maximum of 1000 calls to the API on an hourly basis.\". Which policies could achieve this requirement?","To enforce a per-client limit of **1000 API calls per hour**, a combination of [rate-limit-by-key](https://learn.microsoft.com/en-us/azure/api-management/rate-limit-by-key-policy) and [quota-by-key](https://learn.microsoft.com/en-us/azure/api-management/quota-by-key-policy) policies is required:\n\n- `rate-limit-by-key` is used to control short-term bursts. However, this policy has a **maximum renewal period of 300 seconds (5 minutes)**. To approximate an hourly rate, the hour is divided into 12 intervals. By allowing **80 calls per 5 minutes**, the effective cap becomes 960 calls per hour, which satisfies the requirement of **not exceeding** 1000 calls/hour.\n- `quota-by-key` sets a hard cap on total usage. This policy allows a **minimum renewal period of 300 seconds**, so setting it to **1000 calls per 3600 seconds (1 hour)** provides a strict upper boundary per client.\n\n`counter-key` is required if you want the policy to apply per client (e.g., per subscription, per user, per IP). If you omit counter-key, the policy applies globally to all clients combined, which is rarely useful for rate-limiting or quotas in multi-tenant APIs.\n\nTogether, these policies ensure both **rate smoothing** and **strict quota enforcement**.
