## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability wayback-machine-archive-lookup-472f75cc -d '<json body>'
```

Example prompt: Can you check if 'myoldwebsite.com' is saved in the Wayback Machine and get me the snapshot closest to January 2018?

## When to prefer this

Choose this endpoint when you need to check whether a specific URL has ever been saved by the Internet Archive and retrieve a direct snapshot link. It is ideal when the target page no longer exists, has changed significantly, or you need to verify its historical content. Prefer this over general web scraping when the page is deleted or inaccessible, and over manual Wayback Machine browsing when you need a programmatic, structured result with a precise date.

## Known failure modes

- URL not archived — returns archivada: false with null snapshot fields
- Invalid or malformed URL input — may return error or empty result
- Date format incorrect (not YYYY, YYYY-MM, or YYYY-MM-DD) — may cause lookup failure
- Internet Archive API unavailable or rate-limited — service may time out
- No snapshot near the requested date — returns closest available which may be far from target

## How this service works

Check whether a page is saved in Internet Archive's Wayback Machine and get the snapshot closest to a date (or the latest), with its link. See how a site looked or recover deleted content.

## Output

Returns a JSON object with: the queried URL, whether it is archived (boolean), the direct link to the closest Wayback Machine snapshot, the capture date and time, the HTTP status code of the archived page, the source name (Internet Archive, Wayback Machine), and a link to browse all available captures for that domain.
