API Coverage Map

This map tracks the full public API exported by md and links to dedicated type pages and method pages.

Navigation model:

• Type overview pages: /api/types/<type>/
• Type method pages: /api/types/<type>/<method>
• Shared auxiliaries: /api/aux/<method>

Note: legacy method routes with historical suffixes (for example *-2 and *-min) were discontinued from the documentation navigation.
