Opera API

opera-api.com is a dedicated domain operated by the Opera Group to host and serve application programming interfaces (APIs) for Opera’s entire suite of software products and third-party developer ecosystems. Registered in 2015, the domain uses name servers operated directly by Opera itself, confirming it is an official property of the company rather than an unaffiliated third-party service. With a global traffic rank of #931, the domain sees extremely high volumes of requests, primarily generated by Opera browser installations, developer tools, and integrated services that connect to Opera’s backend infrastructure. These APIs power a wide range of core end-user and developer functionality, including syncing user bookmarks, passwords, and preferences across devices, delivering browser component updates, serving personalized content recommendations, and enabling third-party extensions to connect to Opera’s core browser features. As a backend API domain, it is not intended for public web browsing, which aligns with the lack of publicly accessible content for automated analysis. Opera is one of the oldest remaining independent browser developers, with hundreds of millions of active users worldwide, and this domain forms a critical part of the company’s technical infrastructure that keeps user services connected and functional. Its 10-year operating history and long expiration date confirm it is a permanent, well-maintained core property for the company, with no indication of abandonment or repurposing for harmful use.
