## 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 web-archive-lookup-1c1a07ed -d '<json body>'
```

Example prompt: Can you find me an archived or cached version of https://www.example.com/old-article — the page seems to be down now?

## When to prefer this

Use this endpoint when you need to retrieve a cached or historical version of a specific URL — especially if the live page is unavailable, has changed, or has been deleted. It requires no authentication or subscription, making it ideal for lightweight, on-demand agent workflows that pay per use in USDC.

## Known failure modes

- URL has no available archive — returns success: false or empty data
- Invalid or malformed URL input — likely a 400-level error
- Payment failure via x402 — request not processed
- Archived content is incomplete or truncated
- Target URL is blocked from archiving
