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>
<div id="app"></div>
<!-- Load the Script -->
<script src="https://cdn.jsdelivr.net/npm/@scalar/api-reference"></script>
<!-- Initialize the Scalar API Reference -->
<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>
