+# API rendering
+
+For additional flexibility, django-pattern-library supports rendering patterns via an API endpoint.
+This can be useful when implementing a custom UI while still using the pattern library’s Django rendering features.
+
+The API endpoint is available at `api/v1/render-pattern`. It accepts POST requests with a JSON payload containing the following fields:
+
+- `template_name` – the path of the template to render
+- `config` – the configuration for the template, with the same data structure as the configuration files (`context` and `tags`).
+
+Here is an example, with curl:
+
+```bash
+echo '{"template_name": "patterns/molecules/button/button.html", "config": {"context": {"target_page": {"title": "API"}}, "tags": {"pageurl":{"target_page":{"raw": "/hello-api"}}}}}' | curl -d @- http://localhost:8000/api/v1/render-pattern
+```
+
+The response will be the pattern’s rendered HTML:
+
+```html
+<a href="/hello-api" class="button">
+    API
+</a>
+```
+
+Note compared to iframe rendering, this API always renders the pattern’s HTML standalone, never within a base template.
