- HTML output for direct rendering
- JSON output for templates and CMS
- ETag for efficient revalidation
- Webhooks for change notifications
Example sync
Fetch once, store in your infrastructure, update only when content changes.
GET /v1/domains/{domain}/imprint.html
If-None-Match: "etag-value"
200 OK (or 304 Not Modified)
Cache-Control: max-age=...
ETag: "new-etag"
Use the same approach for JSON, or refresh on webhook events.
Use cases
Multi domain operations and platforms benefit from structured legal publishing.
