Datastreamer provides APIs for social media, news, and blogs. Datastreamer provide both this search API as well as firehose (streaming) APIs, and indexes more than 100M posts per day. In terms of raw data they can provide you with 250GB of data per day and have 1PB of archives over 5 years.
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.
