## 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 url-inspector-industrial-platform-web-tools-82508979 -d '<json body>'
```

Example prompt: Can you inspect this URL for me — https://example.com/report.pdf — and tell me what headers it returns, whether it redirects anywhere, and what the content type and page title are?

## When to prefer this

Choose this endpoint when you need lightweight, machine-payable URL inspection at $0.001 USDC per call via the x402 protocol — ideal for agents that need to check redirect chains, HTTP headers, content type, or page metadata without full content extraction. Prefer this over full scraping endpoints when you only need URL-level metadata rather than page body content.

## Known failure modes

- URL is unreachable or times out — returns error status
- Invalid or malformed URL — schema validation error
- URL returns non-standard HTTP response — partial metadata returned
- Payment not received — x402 payment required error
- URL behind authentication wall — limited metadata returned
- DNS resolution failure for the domain — connection error

## How this service works

Machine-payable x402 utilities for hashing, Base64, UUID generation, unit and timezone conversion, realtime crypto market data, webpage/document extraction, URL-to-Markdown, metadata, RAG ingestion and deterministic website change detection.

## Output

Returns structured JSON with URL inspection results including HTTP status code, response headers, redirect chain hops, final destination URL, content type, page title, and other available metadata about the inspected resource.
