## 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 worlddata402-web-archive-b2ec35c2
```

Example prompt: Can you fetch the archived web content for https://example.com/some-article — I want to see what that page contained even if it's changed or gone now?

## When to prefer this

Choose this endpoint when you need to access historical or cached versions of web pages that may have changed or been removed, especially in an agent context where pay-per-call micropayments via x402/USDC are acceptable. Prefer over general web scraping when the goal is archival retrieval rather than live page content.

## Known failure modes

- URL not found in archive — no cached version available
- Invalid or malformed URL input returns an error
- Rate limiting or payment failure via x402 protocol
- Archived content may be incomplete or truncated for large pages
- Some URLs may be blocked from archiving due to robots.txt restrictions

## How this service works
