Body Builder (beta)

Transform your natural language requests into structured OpenRouter API request objects. Describe what you want to accomplish with AI models, and Body Builder will construct the appropriate API calls. Example: "count to 10 using gemini and opus." This is useful for creating multi-model requests, custom model routers, or programmatic generation of API calls from human descriptions. **BETA NOTICE**: Body Builder is in beta, and currently free. Pricing and functionality may change in the future.
