Rotato – Node.js proxy that rotates LLM API keys on 429 errors

About

Rotato is a Node.js proxy that manages API key rotation for Large Language Model (LLM) services. It automatically switches to a new API key when a 429 error occurs, helping to prevent rate limiting and ensure uninterrupted service. The proxy is designed to be used with LLM APIs that have strict rate limits, such as language translation or text generation services.
