Uncontrolled API traffic can bring even well-built systems to their knees. Whether it’s abusive clients, buggy integrations, scraping bots, or sudden traffic spikes, lack of rate limiting leads to slow responses, outages, and rising infrastructure costs. API Rate Limiting & Throttling ensures fair usage, protects backend resources, and keeps APIs responsive under load. We design and implement robust rate limiting strategies using Django REST Framework or FastAPI, tailored to real-world usage patterns.
Problems Caused by Missing Rate Limits
-
API abuse and brute-force attacks
-
One client consuming disproportionate resources
-
Sudden traffic spikes causing outages
-
Unpredictable infrastructure costs
-
Poor experience for legitimate users
-
No visibility into API usage patterns
