Hypeline Stream API

One authenticated HTTP stream of genuinely new content, deduplicated across sources.

Hypeline turns any source you point it at (born-live firehoses, RSS/JSON feeds, and feed-less HTML pages we diff) into one unified, deduplicated live stream of new content events, delivered over plain HTTP (Server-Sent Events).

Subscribe with a single authenticated curl, filter to the slice you want, reconnect without gaps, and backfill from a cursor.

Latency by source tier

Latency is per source tier. There is no single universal promise:

  • Firehose sources arrive in seconds.
  • RSS / JSON feeds arrive in minutes.
  • Feed-less HTML-diff sources arrive in minutes to tens of minutes.

Every event carries a source_type label so you always know which tier it came from. It is a label, never a behavioural switch.
