# Wayback Archive History - Capture Metadata & Changes — workflow

## Choose this tool

Collect capture timestamps, original URLs, status and digests for SEO migrations, due diligence and research workflows.

Useful output columns: `originalUrl`, `capturedAt`, `httpStatus`, `mimeType`, `digest`, `archiveLength`, `comparisonStatus`, `replayUrl`.

## Practical workflow

Paste exact URLs, choose a small capture window and inspect source-linked archive records. Preserve capturedAt separately from observedAt. Compare complete repeated observations to find newly observed archive entries; verify replay links before relying on content.

## Check the fit

Bounded fast-latest index metadata only. No page text, full-site crawl, exhaustive archive history or replay availability guarantee. Missing captures are not removals.

## Real output sample

One selected row from a 2026-11-06 run. Selected original scalar fields from one actual saved observation; nested data and private artifact links are omitted.

Run: fN93l3VfXGMYcuvEN. Summary status: ok. Incomplete: false.

Dated bounded release evidence for this exact input and build. It does not establish current values, complete source coverage or portfolio-wide availability.
