Weekly launch rankings (winners), and the most upvoted recent launches.
Founder.best launches run on ISO weeks (Monday-Sunday, UTC). This endpoint returns the products that launched in a week, ranked by that week’s score: upvotes received during the week plus the starter bonus included in paid Launch Pro / Pro+ plans. After the week ends, ranks 1-3 are the weekly winners. Without parameters you get the current week, whose ranking is still live.

}next_week is null when you are looking at the current week. Walk the archive with previous_week.api_url rather than computing ISO weeks.
Live products whose launch date falls inside period, ordered by all-time upvotes. Products scheduled for a future week are excluded.
