Quickstart

All you need is a single HTML file to create an amazing API reference:

<!doctype html>
<html>
  <head>
    <title>Scalar API Reference</title>
    <meta charset="utf-8" />
    <meta
      name="viewport"
      content="width=device-width, initial-scale=1" />
  </head>

  <body>







    <script src="https://cdn.jsdelivr.net/npm/@scalar/api-reference"></script>


    <script>
      Scalar.createApiReference('#app', {
        // The URL of the OpenAPI/Swagger document
        url: 'https://registry.scalar.com/@scalar/apis/galaxy?format=json',
        // Avoid CORS issues
        proxyUrl: 'https://proxy.scalar.com',
      })
    </script>
  </body>
</html>
