OpenAPI Spec Validator is a Python library that validates OpenAPI Specs against the OpenAPI 2.0 (aka Swagger) and OpenAPI 3.0.0 specification. The validator aims to check for full compliance with the Specification.

$ pip install openapi-spec-validator

Straight forward way:

$ openapi-spec-validator some.yaml

or more pythonic way:

$ python -m openapi_spec_validator some.yaml

Validate spec:

from openapi_spec_validator import validate_spec

validate_spec(spec_dict)

Add spec_url to validate spec with relative files:

from openapi_spec_validator import validate_spec

validate_spec(spec_dict, spec_url='file:///path/to/spec/openapi.yaml')

You can also validate spec from url:

from openapi_spec_validator import validate_spec_url

validate_spec_url('http://example.com/openapi.json')

If you want to iterate through validation errors:

from openapi_spec_validator import openapi_v3_spec_validator

errors_iterator = openapi_v3_spec_validator.iter_errors(spec)

• openapi-core is a Python library that adds client-side and server-side support for the OpenAPI.
