Natural Language To Api Schema Translation With Type Safety

via “schema-based structured output with cross-language type validation”

Open-source framework for building AI-powered apps in JavaScript, Go, and Python, built and used in production by Google

Unique: Integrates language-native type systems (Zod, Go reflection, Python dataclasses) directly into the generation pipeline rather than using a separate validation layer. Automatically generates JSON schemas from native types for function calling, and validates responses against the original schema definition, ensuring type safety end-to-end.

vs others: Provides tighter type safety than LangChain's output parsers (native types vs string parsing) and automatic schema generation for function calling without manual JSON schema writing.
