## What it is
A Go library for validating JSON documents against JSON Schema, supporting drafts 4, 6, 7, 2019-09, and 2020-12 with full test-suite compliance. It offers extensible vocabularies, custom formats, content assertions, introspectable hierarchical errors, and infinite-loop detection.

## Use cases
- validate  payloads against a  schema in go
- check api request bodies conform to a schema
- validate config files with draft 2020-12 schemas
- register custom formats and vocabularies for schema validation
- get detailed structured validation errors for debugging
- validate base64-encoded or  content assertions

## When to choose
- you need a spec-compliant JSON Schema validator in Go across multiple drafts
- you need custom vocabularies, formats, or regex engines
- you need introspectable, hierarchical validation error output

## When to avoid
- you need schema validation in a language other than Go
- you need JSON Schema code generation rather than runtime validation
