## 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-iframe-f1604390 -d '<json body>'
```

Example prompt: Check the DNS resolution time for the iframe on https://example.com — use the CSS selector '#embed-frame' to target the specific iframe element.

## When to prefer this

Use this endpoint when you specifically need to isolate and measure DNS resolution time for an iframe element on a webpage, particularly when diagnosing slow third-party embeds, ad slots, payment widgets, or maps where DNS latency may be the bottleneck. Prefer this over general page-level DNS checks when the iframe loads from a distinct domain.

## Known failure modes

- Target URL is unreachable or returns a non-200 status
- No iframe element found matching the provided CSS selector
- DNS resolution fails or times out for the target domain
- Invalid or malformed URL provided in the ziel field
- Target IP is private or non-routable, rejected as invalid
- CSS selector matches multiple elements (first match used)

## How this service works

Prüft am Objekt iframe den Befund DNS-Auflösungszeit.

## Output

Returns the DNS resolution time measurement (in milliseconds) for the identified iframe element on the target URL, including relevant performance finding details about how long DNS lookup takes for that embedded resource.
