# Endpoint schema snippet

> Reference an endpoint schema from your API Reference

The `<EndpointSchemaSnippet>` component displays endpoint schemas from your API Reference. By default, it renders the complete schema, or you can use the `selector` prop to display specific parts like request body, response, path parameters, or query parameters. When AI agents fetch the [Markdown version](/learn/docs/ai-features/markdown) of a page, Fern renders the schema — field names, types, and descriptions — as structured content in the Markdown output.

To display any type definition by name (not limited to endpoint schemas), use the [`<Schema>`](/learn/docs/writing-content/components/schema) component.

Markdown-rich field descriptions aren't yet supported and will display as plain text. See the [Request path](#request-path) example below.

```jsx Markdown
<EndpointSchemaSnippet endpoint="POST /chat/{domain}" selector="response.body" />
```

## Properties

**`endpoint`** `string` — required

The endpoint to display, in the format `METHOD /path` (e.g., `POST /chat/{domain}`). If your API uses [namespaces](/learn/api-definitions/overview/project-structure#combined-sdks-from-multiple-apis), prefix with the namespace and `::` (e.g., `payments::POST /chat/{domain}`).

---

**`selector`** `string`

Selects a specific part of the endpoint schema to display. Supported values: `request`, `request.path`, `request.query`, `request.body`, `response`, `response.body`.

---

> Reference an endpoint schema from your API Reference
