AI Structured Outputs Validator
Checks object schemas for `additionalProperties: false` and required property names; does not enforce forbidden keywords or full Structured Outputs rules.
About this ai structured outputs validator
Checks object schemas for `additionalProperties: false` and required property names; does not enforce forbidden keywords or full Structured Outputs rules Validates and converts interface schemas client-side without transmitting private endpoint specifications.
API contract & interface schema logic
Calculates sub-word token counts across major AI tokenizer architectures (OpenAI Tiktoken cl100k_base / o200k_base for GPT-4o, Anthropic Claude byte-pair encodings, and SentencePiece tokenizers for Gemini and Llama). Validates Structured Outputs JSON Schemas and tool definitions for Function Calling APIs, enforcing strict schema constraints (e.g. additionalProperties: false, all properties in required array).
Worked schema conversion scenario
Scenario: A developer checks a narrow set of local object-schema conditions used by strict structured outputs.
Sample input:
Processing: Checks properties and required input shapes, additionalProperties: false, and inclusion of each property name in required; it does not certify full provider support.
Illustrative output:
Schema version & syntax constraints
This is a narrow local checker: object properties/required input shape, additionalProperties false, and declared names in required. It does not validate full JSON Schema syntax, refs, instances, forbidden keywords, root rules, or provider requirements.

Frequently asked questions
What does AI Structured Outputs Validator check?+
It walks submitted JSON Schema objects. At each object-typed node, properties must be an object and required an array of strings when present; additionalProperties must be false, and every declared property must appear in required. It also walks items schemas.
Can you show an input and its result?+
A strict root object with required name and tags, plus a strict object item requiring id inside the tags array, returned valid true with an empty issues array.
Which schema validity rules are outside this check?+
It does not implement complete JSON Schema validation, test example instances, check types, formats, references, recursion, enum values, provider restrictions, token limits or actual model structured-output support.
Does valid true guarantee a model response?+
No. It only means these local strict-object rules found no issue. Provider API behavior, model adherence, refusal handling, retries and application parsing need separate tests.
