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.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
