Frequently Asked Questions
What is JSON Schema Validation?
JSON Schema is a declarative vocabulary that allows you to annotate and validate JSON documents. It enforces rules on required fields, data types, string formats, numeric ranges, and nested structures.
What JSON Schema drafts are supported?
Our validator supports JSON Schema Draft-04, Draft-07, and Draft 2020-12 via the AJV JSON schema engine.
What error diagnostic details are provided?
When validation fails, AJV reports the exact instance path (e.g. /user/email), the violated schema keyword (e.g. format, required), and a descriptive error message.
