## 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 tempo-halowerk-com-dns-resolution-time-check-for-pages-187d52aa -d '<json body>'
```

Example prompt: Can you check how long DNS resolution is taking for https://example.com and tell me if it's within a normal range?

## When to prefer this

Use this endpoint when you need a specific DNS resolution time measurement for a webpage or domain, particularly as part of a web performance audit or when diagnosing slow page load times. It is ideal for checking a single URL's DNS latency rather than running a full page speed audit.

## Known failure modes

- Invalid or unreachable URL returns an error response
- Private or non-public IP addresses may be rejected
- Malformed input schema triggers validation error
- Domain that does not exist results in DNS failure or error finding
- Timeout if the target is extremely slow or unresponsive

## How this service works

Prüft am Objekt seite den Befund DNS-Auflösungszeit.

## Output

Returns a DNS resolution time measurement (timing in milliseconds or similar units) for the specified URL or domain, indicating how long it takes to resolve the domain name as part of the page load process.
