## 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-snapshot-lookup-f8a35bd9 -d '<json body>'
```

Example prompt: Can you check if example.com was archived in the Wayback Machine around January 2016 and get me the link to that snapshot?

## When to prefer this

Use this endpoint when you need to check archival status or retrieve a historical snapshot of a specific URL from the Wayback Machine. It is ideal for content recovery, historical research, fact-checking past web content, or verifying that a page existed at a given time. Prefer this over general web search when the target page is deleted, changed, or you need a time-anchored version.

## Known failure modes

- URL not archived — archived field returns false and snapshot fields are null
- Invalid or malformed URL input — may return an error or no results
- Date format not matching YYYY, YYYY-MM, or YYYY-MM-DD — request may fail or return unexpected results
- No snapshot near the requested date — returns closest available which may be far from the requested date
- Network timeout reaching Internet Archive API — upstream latency spike
