Panduan API Rate‑Limit: Membangun Local Proxy dengan Token Bucket

Many API services implement rate limits to prevent server overload, often resulting in 429 Too Many Requests responses. While exponential backoff is a common solution, it still allows burst requests to reach the upstream. A superior approach involves a local proxy that buffers requests, regulates output rhythmically, and caches responses. This implementation utilizes Python with FastAPI and httpx to create a minimal architecture that effectively manages rate limits and ensures smoother API communication flows.
