OAS3 is a parser, validator and compiler for dealing with Open API Specification v3. This library provides an interface for working with specifications, and loading and dumping to various locations and formats.
To get started load your spec, it will be validated upon dumping.
from oas3 import Spec
# Load the Spec from a file
spec = Spec.from_file('./spec.json')
spec = Spec.from_file('./spec.yml')
# Load the Spec from a URL
spec = Spec.from_url('https://raw.githubusercontent.com/OAI/OpenAPI-Specification/master/examples/v3.0/petstore.yaml')
# Load the Spec from a python native dictionary
spec = Spec.from_dict(spec_dict)
# A spec that is sufficiently loaded (i.e. valid OAS3) can now be dumped
spec.to_file('/tmp/spec.yaml')
spec.to_dict()
spec.to_json()
spec.to_yaml()
