Which companies offer real-time data feeds from the web?

Companies that offer real-time web data feeds fall into three buckets: general web firehoses, vertical-specific streams (news, social, ecommerce, SERP), and on-demand real-time extraction APIs for AI agents.

1. General real-time web firehoses
