Emerging repositories
Small GitHub repositories (under 1,000 stars a week ago, at least 30 days old) gaining stars at least twice as fast as in a usual week, by that ratio; optionally in one topic. The same list as Upstar's Emerging page (or the topic's Emerging tab).

get_repo
A repository's facts
One GitHub repository as Upstar sees it, the same facts as its Upstar page: stars and gains, its usual week, its star total week by week over 12 weeks, its topics and ranks, when Upstar spotted it, its latest release, license, activity and collections. Answers for every repository with an Upstar page, kept-out ones included; blocked ones have none.

輸入參數langdetailcategory
Upstar's search, the same as the site's search bar: topics by whole words (a name, slug, GitHub tag, language or keyword equal to the query, then every word of it in the topic's name, category or description) and every repository with an Upstar page (by name, description, GitHub topics and language; kept-out ones included, blocked ones apart); plain matching, no AI. Repositories: exact name first, then the most stars gained this week.
