## 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-scripts-96fc665c -d '<json body>'
```

Example prompt: Can you check how long the DNS resolution takes for the script at https://cdn.example.com/app.js and tell me if there's a delay?

## When to prefer this

Use this endpoint when you specifically need to measure DNS resolution time for a script (JavaScript) resource, as opposed to other asset types like documents, images, stylesheets, or API responses. It is the right choice when diagnosing slow script loading caused by DNS latency, auditing third-party script dependencies, or monitoring CDN DNS performance over time.

## Known failure modes

- Invalid or unreachable URL returns an error
- Domain does not resolve (NXDOMAIN) results in failure response
- Malformed input schema causes validation error
- Script URL exceeds maximum length of 2048 characters
- Non-public or private IP addresses may be rejected
- CSS selector matches no element, falls back to first match or errors

## How this service works

Prüft am Objekt skript den Befund DNS-Auflösungszeit.

## Output

Returns the DNS resolution time (in milliseconds) measured for the specified script resource, along with associated performance finding metadata for that object.
