## 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-d24ef56e
```

Example prompt: Can you give me a summary of how long https://example.com has been archived on the Wayback Machine — I want to know when it was first and last captured?

## When to prefer this

Use this endpoint when you need a quick high-level overview of a URL's archive lifespan — specifically its first and last capture dates and direct links to those snapshots — without needing the full chronological list of all snapshots. Prefer over the full history endpoint when only boundary dates matter.

## Known failure modes

- URL has never been archived — no archive data returned
- Invalid or malformed URL input — query rejected
- Wayback Machine API unavailable or rate-limited — timeout or error response
- URL parameter missing from query — 400 bad request
