jsonschema

jsonschema is the most complete and spec-compliant JSON Schema validator for Python, supporting Draft 3, 4, 6, 7, 2019-09, and 2020-12. The current stable release is 4.26.0 (requires Python ≥ 3.10). Releases follow semantic versioning and ship frequently via GitHub; minor releases are expected to be backwards-compatible while major versions may carry deprecations that become removals.
