Web Archive Scraper

Search the Wayback Machine (Internet Archive) for archived snapshots of websites. Fetch cached page content to find customer lists, testimonials, partner directories, and other information from sites that have changed or shut down.

Quick Start

Only dependency is requests. No API key needed.

# Find all snapshots of a URL
python3 skills/web-archive-scraper/scripts/search_archive.py \
  --url "https://botkeeper.com/customers"

# Search with date range
python3 skills/web-archive-scraper/scripts/search_archive.py \
  --url "https://botkeeper.com" --from 2025-01-01 --to 2026-02-01

# Search all pages under a domain (prefix match)
python3 skills/web-archive-scraper/scripts/search_archive.py \
  --url "https://botkeeper.com" --match prefix --limit 50

# Fetch the actual archived page content
python3 skills/web-archive-scraper/scripts/search_archive.py \
  --url "https://botkeeper.com/customers" --fetch

# Output formats
python3 skills/web-archive-scraper/scripts/search_archive.py --url URL --output json
python3 skills/web-archive-scraper/scripts/search_archive.py --url URL --output csv
python3 skills/web-archive-scraper/scripts/search_archive.py --url URL --output summary

How It Works

CDX API search — Queries web.archive.org/cdx/search/cdx for snapshots matching the URL
Filtering — Filters by date range, HTTP status code, and MIME type
Dedup — Collapses to one snapshot per day by default to avoid redundant results
Content fetch — Optionally fetches the raw archived HTML (using id_ modifier to skip Wayback toolbar)
Text extraction — Strips HTML tags for readable text output when fetching content
