The DynaMed API GET /v2/content/articles endpoint returns metadata for articles published within a specified date range.

Fields

The updatedAt parameter indicates the last time the page was published. Dates must conform to ISO 8601. An example date is 2021-12-17T22:50:42.511Z or 2021-12-17. If neither updatedSince nor updatedBefore are provided, all updates are returned. If no updatedBefore is supplied, then all dates from the updateSince until today's date are returned. If no updatedSince is provided, then all dates up to the updatedBefore are returned.

Paging

Up to 100 items may be returned in a request. If more than 100 are returned, the totalItems indicates how many items there are to retrieve. The page parameter in the response indicates the page returned. To get the next page of items, add one to the page. Each page has 100 items.
