Turn any website into an API
Most of the web has no API. Hypeline gives it one. Point it at a page, a feed or a push source and get a clean, deduplicated stream of new content you can consume like any other API, over SSE, cursor catch-up and signed webhooks.
From a URL to an event stream
Point it at a URL
Give Hypeline any source you care about: an RSS, Atom or JSON feed, a plain web page with no feed at all, or a live push source. Any language, any region.
It detects and extracts
Hypeline auto-detects the format, fetches politely, and pulls the real content out of the page, dropping boilerplate, navigation and template noise.
It keeps only real changes
Each source is fingerprinted and deduplicated, so you get genuinely new content as discrete events instead of the same item twice or a diff full of timestamp churn.
You consume events
Read the stream over Server-Sent Events, catch up or backfill with a cursor, or receive HMAC-signed webhooks. The event schema is stable and versioned.
Everything you would build yourself, already built
| What you need | Rolling your own | With Hypeline |
|---|---|---|
| Handle any source format | A parser per feed type, plus a scraper for pages with no feed | One endpoint, format auto-detected |
| Extract the real content | Custom boilerplate removal per site | Built-in content extraction |
| Detect genuine changes | Your own diffing and dedup, tuned to avoid noise | Fingerprinted, deduplicated for you |
| Deliver in real time | Build and operate SSE, webhooks and retries | SSE, cursor and signed webhooks out of the box |
| Stay polite and safe | robots.txt, backoff, SSRF protection | Handled at the fetch layer |
Frequently asked questions
What kinds of websites can I turn into an API?
Any public source you point Hypeline at, in any language or region. It handles RSS, Atom and JSON feeds, feed-less HTML pages that it diffs for real changes, and live push sources. It ingests only free, open, public content.
Do I need the site to have an RSS feed?
No. If a feed exists Hypeline uses it, but feed-less pages work too: it fetches the page, extracts the main content, and detects genuinely new material by comparing fingerprints over time.
How do I receive the data?
Over plain HTTPS. Subscribe with Server-Sent Events for a live feed, catch up or backfill with a cursor, and receive HMAC-signed webhooks for server-to-server delivery. Every event follows one stable, versioned schema.
Is it polite to the sites it watches?
Yes. Fetching respects robots.txt, rate limits and conditional requests, with adaptive per-source scheduling so hot sources are checked often and quiet ones back off.
