# Verify Historical Claims

In disputes, investigations, and fact-checking, the question often arises: "What did the website actually say at that time?" Companies change terms retroactively, public figures edit their statements, and organizations revise published positions. The Wayback Machine provides timestamped evidence of what was actually published.

ToolRouter's check_availability skill confirms whether a page was archived at the relevant time, and search_captures finds all available snapshots. This gives you verifiable, timestamped evidence of published content that can be used in legal proceedings, journalistic investigations, and fact-checking.

This workflow is essential for journalists verifying claims, legal teams gathering evidence, fact-checkers establishing what was published when, and researchers documenting historical records. Archived web content carries timestamps that establish a clear record of what was publicly available at a given point in time.
