Ethan Palm 3dc3852b7a SEO descriptions (#4028)
* Improve SEO descriptions across 47 pages

Curated descriptions from two bot-generated PRs (#3908, #3949),
selecting the best approach for each page:
- Added missing title and description frontmatter to 10 API reference pages
- Benefit-focused descriptions for integration pages (not implementation-heavy)
- Accurate REST-aligned titles for API endpoints (Export, List, Trigger, etc.)
- Expanded short descriptions to 50–160 character range throughout

* copyedit

* Update custom-domain.mdx

* Fix analytics API page titles to match spec summaries

"Export" was inaccurate — spec uses "Get" for both endpoints.
Also updated descriptions to use "Retrieve" for consistency.

Configure your `vercel.json` file to proxy requests from your main domain to your documentation at a subpath.
## vercel.json file
The `vercel.json` file configures how your project builds and deploys. It sits in your project's root directory and controls various aspects of your deployment, including routing, redirects, headers, and build settings.
We use the `rewrites` configuration in your `vercel.json` file to proxy requests from your main domain to your documentation.
Rewrites map incoming requests to different destinations without changing the URL in the browser. When someone visits `yoursite.com/docs`, Vercel internally fetches content from `your-subdomain.mintlify.dev/docs`, but the user still sees `yoursite.com/docs` in their browser. This is different from redirects, which send users to another URL entirely.
## Configuration
### Host at `/docs` subpath
1. Navigate to [Custom domain setup](https://dashboard.mintlify.com/settings/deployment/custom-domain) in your dashboard.
2. Click the **Host at `/docs`** toggle to the on position.

</Frame>
3. Enter your domain.
4. Select **Add domain**.
5. Add the following rewrites to your `vercel.json` file. Replace `[subdomain]` with your subdomain, which is found at the end of your dashboard URL. For example, `dashboard.mintlify.com/your-organization/your-subdomain` has a domain identifier of `your-subdomain`.
```json
{
"rewrites": [
{
"source": "/docs",
"destination": "https://[subdomain].mintlify.dev/docs"
},
{
"source": "/docs/:match*",
"destination": "https://[subdomain].mintlify.dev/docs/:match*"
}
]
}
```
The `rewrites` configuration maps the `/docs` subpath on your domain to the `/docs` subpath on your documentation.
- **`source`**: The path pattern on your domain that triggers the rewrite.
- **`destination`**: Where the request should be proxied to.
- **`:match*`**: A wildcard that captures any path segments after your subpath.
For more information, see [Configuring projects with vercel.json: Rewrites](https://vercel.com/docs/projects/project-configuration#rewrites) in the Vercel documentation.
### Host at custom subpath
To use a custom subpath (any path other than `/docs`), you must organize your documentation files within your repository to match your subpath structure. For example, if your documentation is hosted at `yoursite.com/help`, your documentation files must be in a `help/` directory.
Use the generator below to create your rewrites configuration. Add the rewrites to your `vercel.json` file.
