## 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 saylor-innovations-web-intelligence-website-history-internet-archive-4c99bbe1
```

Example prompt: How long has stripe.com existed and what major changes have happened on it? Pull the Internet Archive history — I want to see the first and last snapshot dates, how many versions exist per year, and any recent content changes with links.

## When to prefer this

Choose this endpoint when you need structured, parsed Internet Archive data about a website's history without manually querying the Wayback Machine CDX API. It is ideal for due diligence, competitive research, domain age verification, or content change tracking where you need first/last seen dates, per-year version counts, and recent change diffs — all in one clean JSON response at $0.003 per call.

## Known failure modes

- URL not found in Internet Archive — returns archived: false with null history fields
- Invalid or malformed URL input causes a 400-level error
- Internet Archive upstream timeout or unavailability may cause delayed or failed response
- Very new domains with no archive history return empty/null history object
