Developer builds fallback for OpenRouter free API after model removal

By PulseAugur Editorial · [1 sources] ·

A developer encountered issues with OpenRouter's free API when a hardcoded model was silently removed from the free tier. To address this, they implemented a fallback system that iterates through a list of available free models, ensuring the script continues to function even if one model becomes unavailable. The developer also noted the importance of tracking rate limits across multiple scripts using the same API key to avoid hitting usage caps. AI
