JSON Schema Validator
AI / AgentValidate any JSON value against a JSON Schema (Draft-07): types, required fields, patterns, formats, and nested rules.
This lives in the AI tools category specifically because agent pipelines that call tools or parse structured LLM output need to validate the result against a contract, and this does that: paste a JSON value and a Draft-07 schema side by side and get back the exact rule and path that failed, not just a pass/fail. Standard `format` keywords like `email` and `date-time` are checked, though format validation is technically an annotation-only feature in the spec and enforcement varies slightly across validator implementations. It's the same core validation job as the JSON category's JSON Schema Validator tool, positioned here for agent and pipeline debugging use cases. Pair it with the JSON Schema Generator to draft a schema from a description first, then validate real sample payloads against it here. For bulk validation of many records, the REST API or SDK is the better fit than this one-off browser tool.
How to use JSON Schema Validator
- 1.Paste a JSON value and a Draft-07 JSON Schema side by side to check whether the value satisfies types, required fields, and nested rules.
- 2.Use it to debug why an API response is failing validation in your backend by seeing the exact rule and path that failed.
- 3.Pair it with the JSON Schema Generator to first draft a schema from a description, then validate real sample payloads against it here.
