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/>`__.

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.
