JSON Schema
A declarative language that defines the expected structure, constraints, and data types for JSON documents to ensure consistency and validation.
Think of It Like This
Like a strict bouncer at a club checking that every ID has the right format, birthdate, and state seal before letting anyone in.
In AI ecosystems, JSON schema is heavily used to enforce structured outputs from LLMs and define the expected parameters for tool calling. By forcing the model to adhere to a schema, downstream applications can safely parse and execute the generated data. It dramatically reduces the parsing errors commonly associated with raw text generation.
