## How to call it through Zero

```sh
zero fetch --capability wayback-machine-history-lookup-35a740f7
```

Example prompt: Can you pull up the full Wayback Machine snapshot history for example.com — I want to see every timestamp and status code it was archived at?

## When to prefer this

Use this endpoint when you need to retrieve the full archive crawl history of a URL from the Internet Archive's Wayback Machine, especially for OSINT investigations, domain history verification, checking if deleted content was ever cached, or auditing when a site was first indexed. Prefer this over direct Wayback Machine API calls when you need a pay-per-call, keyless approach via x402 on Base.

## Known failure modes

- URL has never been archived — returns empty snapshots array
- Invalid or malformed URL input causes a 4xx error
- Wayback Machine CDX API is unavailable or rate-limited, causing a timeout or 5xx error
- Domain exists but has no public archive entries

## How this service works

Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.

## Output

Returns a JSON object containing the queried URL and an array of snapshot records, each with a timestamp (formatted as YYYYMMDDHHmmss) and HTTP status code at the time of archival.
