OpenSearchServer is an open-source search engine based on continuously improving open-source technology. Through their SaaS center users can access a public API. The Screenshot API allows users to make a screenshot capture of a Web page. The user can choose to capture only the visible part of the page or the full content. The service uses REST calls and returns a PNG image which can still be reduced (to generate a thumbnail). An account is required with service, and API Key is used to access the API.
