Hard limits on total API usage over a billing period, often tied to pricing tiers.
An API quota is a limit on how much of an API you can use within a period (per day, per month, per project, per user, etc.). Quotas protect providers from abuse and help them manage capacity and pricing. They can also prevent your app or integration from running up unexpected costs.
If you build tools or dashboards, quotas should be treated as a product constraint: design for graceful degradation rather than hard failures.
