Jagex is a British video game developer and publisher headquartered in Cambridge, England, best known as the studio behind RuneScape and Old School RuneScape - persistent, community-shaped online worlds that have run for over two decades. Beyond the games, Jagex operates a set of public, read-only RuneScape web-data APIs: the Grand Exchange item price and catalogue endpoints (for both RuneScape and Old School RuneScape), the RuneScape and Old School RuneScape Hiscores, and the RuneMetrics player-profile service. These unauthenticated JSON and CSV endpoints power a large third-party ecosystem of price trackers, fan sites, clan tools, and community applications. Jagex was surfaced as a portfolio company of Insight Partners.
