US Zipcode, County, City, and State Boundaries API: A simple & very fast API that will allow you to integrate multiple GeoJson US boundaries results into your apps and systems. This API is designed to be used programatically for optimal performance. When using the MashApe UI for queries expect significant latency issues on large result sets!
This API can be used to compute a set of readability metrics for a given text. We currently support the following metrics: Automated Readability Index, Coleman-Liau Index, Flesch–Kincaid Grade Level, Flesch Reading Ease, Gunning-Fog Index, SMOG score, and SMOG Index. The service is deployed at Google App Engine and available at https://ipeirotis-hrd.appspot.com/ The code and documentation are available on Github at https://github.com/ipeirotis/ReadabilityMetrics
DuckDuckGo Zero-click Info includes topic summaries, categories, disambiguation, official sites, !bang redirects, definitions and more. You can use this API for many things, e.g. define people, places, things, words and concepts; provides direct links to other services (via !bang syntax); list related topics; and gives official sites when available.
Get favicon-related information about a particular website. The most obvious service is getting the icons of a website. In addition to the classic favicon, the API can also get the icons for iOS, Android Chrome, Windows and Safari pinned tabs. This can be handy to get the high resolution logo of a website. The API also allows you to get an icon preview. For example, what if you add a website to the home screen of an Android device using Chrome? How would it look like? The API generates such image.
Returns well-parsed whois fields in XML and JSON formats. Use it to track domain registrations, check domain name availability, detect credit card fraud, locate users geographically. The service automatically follows the whois registry referral chains until it finds the correct whois registrars with the most complete whois data. Works over basic HTTP and avoices firewall-related problems of accessing Whois servers on port 43.
