Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-status-checker-adam-hale-tools-32765414
```

Example prompt: Can you check whether these URLs are up and where they redirect to: apify.com, example.com, google.com?

## When to prefer this

Choose this endpoint when you need fast, bulk HTTP status and redirect-chain checks for up to 10 public URLs without spinning up a full crawler. It is ideal for link validation, pre-launch checks, and redirect audits where you need the full hop-by-hop chain and final URL, not page content.

## Known failure modes

- Private/internal IP addresses or hostnames rejected (only public hosts on ports 80/443 accepted)
- More than 10 URLs in a single request not supported
- Malformed URLs cause individual result failures
- DNS failures or timeouts result in failed entries in the results array
- Non-standard ports rejected

## How this service works

Guides and free-to-run Apify actors for bulk tech stack lookup, sitemap URL export to CSV, TED and UK Find a Tender search, and RSS-to-JSON feed monitoring.

## Output

Returns a JSON object with a count of checked URLs, number succeeded and failed, and per-URL results including whether the request succeeded, the input URL, final resolved URL, HTTP status, redirect chain (each hop with URL and status code), redirect count, and response time in milliseconds.
