About

Openapi-schema-validator is a Python library that validates schema against:

• OpenAPI Schema Specification v3.0 <https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.0.md#schemaObject>__ which is an extended subset of the JSON Schema Specification Wright Draft 00 <http://json-schema.org/>__.
• OpenAPI Schema Specification v3.1 <https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#schemaObject>__ which is an extended superset of the JSON Schema Specification Draft 2020-12 <http://json-schema.org/>__.

Installation ############

Recommended way (via pip):

.. code-block:: console

pip install openapi-schema-validator

Alternatively you can download the code and install from the repository:

.. code-block:: console

pip install -e git+https://github.com/python-openapi/openapi-schema-validator.git#egg=openapi_schema_validator

Usage

To validate an OpenAPI v3.1 schema:

.. code-block:: python

from openapi_schema_validator import validate

A sample schema

schema = { "type": "object", "required": [ "name" ], "properties": { "name": { "type": "string" }, "age": { "type": ["integer", "null"], "format": "int32", "minimum": 0, }, "birth-date": { "type": "string", "format": "date", }, "address": { "type": 'array', "prefixItems": [ { "type": "number" }, { "type": "string" }, { "enum": ["Street", "Avenue", "Boulevard"] }, { "enum": ["NW", "NE", "SW", "SE"] } ], "items": False, } }, "additionalProperties": False, }

If no exception is raised by validate(), the instance is valid.

validate({"name": "John", "age": 23, "address": [1600, "Pennsylvania", "Avenue"]}, schema)

validate({"name": "John", "city": "London"}, schema)

Traceback (most recent call last): ... ValidationError: Additional properties are not allowed ('city' was unexpected)

By default, the latest OpenAPI schema syntax is expected.
