Zally RESTful API (Zally Server)

In order to lint an API specification you just have to send a HTTP POST request to a running instance of Zally Server. Here is a request example:

curl -X POST \
  -H "Content-Type: application/json" \
  --data '{"api_definition_string": "openapi: 3.0.2"}' \
    localhost:8000/api-violations

And here is a response example:

{
  "external_id": "9b26b489-8ccf-4a2f-be13-5b541ef543bd",
  "message": "",
  "violations": [
    {
      "title": "Use Semantic Versioning",
      "description": "Semantic versioning has to be used in format MAJOR.MINOR(.DRAFT): version is missing",
      "violation_type": "MUST",
      "rule_link": "https://zalando.github.io/restful-api-guidelines/#116",
      "paths": [
        "/info/version"
      ],
      "pointer": "/info/version",
      "start_line": 1,
      "end_line": 1
    }
  ],
  "violations_count": {
    "must": 1,
    "should": 0,
    "may": 0,
    "hint": 0
  }
}

Please consult Zally API specification. for further information. The well-defined API explains various linting variants and usage of other features like permalinks to results, statistics, etc.

Web UI

Zally Web UI is the most intuitive way of using Zally. The user interface is self-explaining.

CLI

You can download Zally CLI from the release page. After unpacking and adding the binary to the $PATH you can lint an API specification by typing:

zally \
  --linter-service localhost:8000 \
  --format pretty \
  lint api.yaml

You can also list supported rules by executing zally rules.

See zally --help for more information.
