King Proxies validates activity and tests performance of public HTTP, HTTPS, Socks, and FTP proxies. Results are updated every 2 hours, and proxies are continuously ranked according to speed. The King Proxies RESTful API allows developers to search and filter proxies by location, social integration presence, performance, and request type options. The API delivers a list of the most reliable proxies in JSON, CSV, or XML formats, and is consumable through Mashape.
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.
