Script Execution

bash

npx tsx scripts/oldest-newest.ts <url>

Run from the wayback plugin directory: ~/.claude/plugins/cache/wayback/

How It Works

Queries the CDX API twice:

•Oldest capture: limit=1 with default ascending sort
•Newest capture: limit=1 with fastLatest=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.
