## How to call it through Zero

```sh
zero fetch --capability wayback-machine-website-history-lookup-2f565ba9
```

Example prompt: Can you pull the full Wayback Machine history for shopify.com — I want to know when it first appeared online, how many snapshots exist, and a monthly timeline of the last 50 archived versions?

## When to prefer this

Use this endpoint when you need structured historical archive data about a website — especially first/last appearance dates, version count, and a monthly snapshot timeline — sourced directly from the Internet Archive Wayback Machine. Ideal for domain due diligence, brand history research, competitive intelligence, or change tracking. Prefer this over manual Wayback Machine browsing when you need machine-readable JSON output without an API key.

## Known failure modes

- URL not found in Wayback Machine archive — returns empty or zero snapshots
- Invalid URL format — query param missing or malformed
- Limit parameter out of range (must be 1–100) — validation error
- Payment failure via x402 — call not processed
- Timeout if Wayback Machine CDX API is slow to respond
- Private or robots.txt-excluded domains may have limited or no snapshots

## How this service works

The archived history of any website from the Internet Archive Wayback Machine: first-seen date, last-seen date, total snapshots, how many distinct versions the page went through, and a timeline of snapshot links (one per month). Great for domain due-diligence, brand history and change tracking. JSON response. $0.02 USDC per call, pay via x402, no API key.

## Output

A JSON object containing the website's first-seen date, last-seen date, total snapshot count, number of distinct versions, and a chronological timeline of snapshot links (one per month, up to the requested limit).
