Validate AI JSON Output Before Taking Action
Parse AI-generated JSON and validate common JSON Schema rules before a workflow executes a model-produced tool call or downstream action.
When to use it
Use this between model generation and an action. The endpoint can validate required fields, types, enums, properties, additional properties, array sizes, string patterns, and numeric limits.
Important limitation
It intentionally supports a practical subset of JSON Schema rather than every keyword. Unsupported advanced schema features should be validated with a full schema implementation in your application.
