# Fields

Use `ParamField` and `ResponseField` to document structured interfaces inside prose-heavy docs.

<ParamField path="projectId" type="string" required>
  The project identifier in the route path.
</ParamField>

<ParamField query="draft" type="boolean" default="false">
  When true, the preview draft is returned instead of published content.
</ParamField>

<ParamField header="authorization" type="string" required>
  Standard bearer token header.
</ParamField>

<ResponseField name="slug" type="string" required>
  Canonical page slug.
</ResponseField>

<ResponseField name="headings" type="NavHeading[]">
  Flat heading list used by Holocron's table of contents.
</ResponseField>

## Holocron differences

* Holocron supports the common field metadata: location, type, required, deprecated, and default.
* Mintlify documents a wider prop surface around response formatting. Holocron currently keeps the rendering intentionally small and readable.
