Unified text diff
A line-by-line diff of the page content, so you see exactly what was added, removed, or rewritten.
POST /v1/diff
Track what changed between two snapshots.
Compare a page against an earlier snapshot and get a clean diff of what moved.
Give your agent a way to watch the web for change. Send a URL plus a previous extraction result and get back a unified text diff, metadata changes, added and removed links, and a word count delta. Built in Rust, with JS rendering and bot protection handled automatically.
What you get
Everything in one call.
Metadata changes
Each changed metadata field comes back with its old and new value, plus the word count delta.
Link tracking
Separate lists of links added and links removed tell you when new pages appear or old ones drop off.
Snapshot-based, stateless
You supply the baseline and choose when to compare it. Hosted requests may still appear in cache and request history.
How it works
From URL to output in four steps.
01
Send URL and baseline
POST the target URL along with a previous extraction result from an earlier /v1/scrape call.
02
We re-fetch the page
The current version is scraped fresh, handling JS rendering and bot protection on the way.
03
Diff the two versions
Content, metadata, and links are compared against your baseline to find every change.
04
Get the change report
The response returns a Changed or Unchanged status with the full diff and link deltas.
API
One request, structured back.
POST /v1/diff
Save the JSON output of a /v1/scrape call as your baseline, then POST that URL plus the saved result to /v1/diff. You get back a Changed or Unchanged status with a unified text diff, metadata changes, and the links added or removed since the snapshot.
