How It Works
Queries the CDX API twice:
- Oldest capture:
limit=1with default ascending sort - Newest capture:
limit=1withfastLatest=true
Calculates the day span between first and last capture to show how long the URL has been tracked.
Caching
CDX API responses are cached for 1 hour. Use --no-cache to bypass.
