Without it, a single misbehaving client — a misconfigured retry loop, a runaway script, a bad actor — can degrade or take down your API for every other consumer. With it, you define the boundaries of acceptable usage and enforce them automatically. For any API exposed to more than one consumer, rate limiting is infrastructure, not a feature.</p>
