Superfeedr
Superfeedr is a feed API for applications that publish content, consume feeds, or track mentions across feeds.
What Superfeedr is
Superfeedr is a feed API for applications that publish content, consume feeds, or track mentions across feeds. It supports RSS, Atom, and JSON, and sends feed updates through push notifications and webhooks. Publishers can use hosted PubSubHubbub hubs to notify subscribers when content is new or updated. Subscribers submit feed URLs and receive content as Atom or JSON. Trackers can filter mentions across millions of feeds using included or excluded terms, exact or fuzzy matching, and language filters. Hub analytics cover subscriber and subscription counts and timeframes, with JSON export; publishers can also export subscriber information. Pro Hubs add custom CNAMEs, landing pages, and subscription controls. The service uses push and ping to detect updates, though it may poll high-frequency feeds as often as every minute. Superfeedr is available on the web and through an API. Hosted Hub and basic Subscriber use have free options; Tracker is $2.00 per month per tracking feed, with 2,000 monthly notifications included. Pro Hub is $200.00 per month.
