Take a look at this API: [url]https://www.bungie.net/platform/destiny/help/HelpDetail/GET?uri=Stats%2fActivityHistory%2f%7bmembershipType%7d%2f%7bdestinyMembershipId%7d%2f%7bcharacterId%7d%2f[/url] You can filter the response by game mode but not time frame, you will always get most recent activity first. This is only for a specific character, not all characters together. The response includes the instance ID which you can then use to pull the specific PGCR to get more details about a particular activity. This is the best Bungie.net has to offer. However, as others on this thread point out, there are several sites that just bulk download all of the PGCRs and then provide other ways to query that same data.
