Overview
Validates any JSON document against any JSON Schema, draft-07 or 2020-12. Returns valid boolean, total error count, and per-error instance_path + schema_path + keyword + message. Powered by @cfworker/json-schema (MIT), a spec-walker validator with built-in format keyword support (email / uri / date / uuid / etc.). Check whether an LLM's structured output matches the spec you asked for, validate an API response against your documented schema, or add a verification gate to an agent pipeline. 200KB
