# Runtime API Examples
This page demonstrates usage of some of the runtime APIs provided by VitePress.
The main `useData()` API can be used to access site, theme, and page data for the current page. It works in both `.md` and `.vue` files:
```md
<script setup>
import { useData } from 'vitepress'
const { theme, page, frontmatter } = useData()
</script>
## Results
### Theme Data
<pre>{{ theme }}</pre>
### Page Data
<pre>{{ page }}</pre>
### Page Frontmatter
<pre>{{ frontmatter }}</pre>
```
<script setup>
import { useData } from 'vitepress'
const { site, theme, page, frontmatter } = useData()
</script>
## Results
### Theme Data
<pre>{{ theme }}</pre>
### Page Data
<pre>{{ page }}</pre>
### Page Frontmatter
<pre>{{ frontmatter }}</pre>
## More
