Gnip is a social media API aggregation company that gathers data from social media sites and provides it to customers in a centralized location. It partners with Twitter to provide access to Twitter's full firehose of data. Gnip costs vary depending on the amount and type of data a business needs, ranging from a few thousand to over $100,000 per month. While useful for businesses to analyze brand sentiment and marketing efforts, Gnip would not be practical or affordable for individual use.
