Python library for Web APIs leveraging OpenAPI/Swagger specification

Project description

Python library for Web APIs leveraging OpenAPI/Swagger specification, enabling you to:

  • validate an OAS 2.0 document
  • prune an OAS 2.0 document of its unused elements
  • filter endpoints of an OAS 2.0 document to generate a subset of the API
  • [todo] detect changes between two OAS 2.0 documents (what’s new, changed, deprecated, removed)
  • [todo] merge multiple OAS 2.0 documents together
  • [todo] rate/score quality of an OAS 2.0 document (documentation coverage, good practices,…)
  • [todo] transform an OAS 2.0 document (add x-… items, rename paths, rewrite basePath, …)
  • [todo] add/remove securityDefinitions on an OAS 2.0 document

Install oasapi from PyPI with:

pip install oasapi

You can also install the in-development version with:

pip install

OAS Document validation

Validate an OAS 2.0 Document (in JSON or YAML format) with:

python -m oasapi validate samples/swagger_petstore.json

or if you prefer with the oasapi script:

oasapi validate samples/swagger_petstore.json

or with the sdementen/oasapi Docker image (available on Docker Hub):

docker run sdementen/oasapi validate

You can also pipe a swagger to the command (if oasapi cannot retrieve the file by itself):

type samples/swagger_petstore.json | oasapi validate -
type samples/swagger_petstore.json | docker run -i sdementen/oasapi validate -
curl | oasapi validate -
curl -s | docker run -i sdementen/oasapi validate -

OAS Document filtering

Similarly, you can use the filter command to filter an OAS 2.0 document and keep only specific operations. For instance, to keep only operations with the tag ‘pet’, the security scope at most ‘read:pets’ and the operations matching the regepx “(GET|PUT) .*petid.*” (all paths containing ‘petid’ with verb GET or PUT), run:

oasapi filter -o new_swagger.json --tag pet --security-scope read:pets --path "(GET|PUT) .*petid.*"

(you will see that the new_swagger.json has only one operation left GET /pet/{petId}).

OAS Document pruning

Another useful command is pruning, which takes an OAS 2.0 document and prune it of its unused elements as:

oasapi prune -o new_swagger.json
