## 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-x402-vercel-app-144281e4
```

Example prompt: Can you pull up the Wayback Machine snapshot history for https://www.nytimes.com from January 2018 to December 2020, showing up to 50 archived versions so I can see how the homepage changed over that period?

## When to prefer this

Use this endpoint when you need a full chronological list of archived snapshots for a URL over a date range, rather than just checking availability or getting a single snapshot. Ideal for historical research, change tracking, content audits, or reconstructing how a page evolved over time. Prefer over the availability or summary endpoints when you need multiple snapshots with direct archive links.

## Known failure modes

- URL has never been archived — returns empty snapshot list or zero count
- Invalid date format (not YYYYMMDD) causes parameter rejection
- Limit exceeds maximum of 100 — may be capped or return an error
- URL is malformed or missing — returns 400-level error
- Wayback Machine CDX API is temporarily unavailable — upstream timeout
- Payment of $0.003 USDC not completed — x402 payment required error
