## 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 pixels-gateway-clawca-sh-link-inspector-8d23ee77 -d '<json body>'
```

Example prompt: Can you inspect this URL for me — https://example.com/some-page — and tell me if it redirects anywhere, what content type it returns, how many words are on the page, and give me a content hash so I can track changes?

## When to prefer this

Use this endpoint when you need to quickly audit a URL's redirect behavior, verify its content type, extract basic metadata, or generate a content hash for change tracking — without needing to render JavaScript or scrape full structured data. Prefer it over full scraping tools when you only need lightweight link inspection signals.

## Known failure modes

- URL must start with https:// — plain http URLs are rejected
- Non-public or private IP URLs may fail or be blocked
- If the target URL is unreachable or returns an error status, inspection fails
- Very large pages may time out or return incomplete word counts
- Malformed URI input causes validation error

## How this service works

Inspect a public HTTPS URL for redirects, metadata, content type, word count, and content hash.

## Output

Returns structured data about the inspected URL including the redirect chain (all hops), HTTP metadata, detected content type, word count of the page content, and a content hash for change detection.
