You may want to build an affiliate feed, an XML product feed, or a custom front end from your HomeRunner property data.
What HomeRunner provides. HomeRunner does not generate affiliate or XML product feeds natively, and there is no XML export to switch on. Your property data is already available as a read-only API on your own site at https://<your-site>/wp-json/wp/v2/properties. The endpoint is public and read-only, so no key is needed.
Getting all properties. Add ?per_page=100&page=N to walk the full set. The response headers X-WP-Total and X-WP-TotalPages tell you how many there are.
Multilingual sites. Add ?lang=nl, ?lang=de, ?lang=en and so on to get correctly localized property URLs for each language.
