Detect changes

Snapshot Archive automatically compares consecutive snapshots and generates visual diffs. Use the diffs API to find pages that changed, filter by change magnitude, and build automated monitoring pipelines.

Find significant changes this week

bash
# Significant diffs in the past 7 days, sorted by change %
curl "https://api.snapshotarchive.com/v1/monitors/42/diffs?created_after=2026-09-24&is_significant=true&sort=change_percent&order=desc" \
  -H "Authorization: Bearer YOUR_API_KEY" -H "Accept: application/json"

# Only large changes (>10%)
curl "https://api.snapshotarchive.com/v1/monitors/42/diffs?min_change_percent=10" \
  -H "Authorization: Bearer YOUR_API_KEY" -H "Accept: application/json"
Tip: Minor changes like timestamp updates or ad rotations often register as 0.1–2% change. For meaningful content changes, filter with min_change_percent=3 or use is_significant=true.
