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 tempo-halowerk-com-verbindungsaufbauzeit-f-r-skripte-pr-fen-7d5f0624 -d '<json body>'
```

Example prompt: Can you check the connection setup time (Verbindungsaufbauzeit) for the script at https://example.com/assets/main.js and tell me how long it takes to establish a connection?

## When to prefer this

Use this endpoint when you specifically need to isolate and measure the connection establishment phase (TCP/TLS handshake) for a script resource, as opposed to total load time or DNS resolution time. It is appropriate when diagnosing whether a third-party or first-party script host has slow connection setup contributing to page performance issues.

## Known failure modes

- Script URL is unreachable or returns a non-200 status — measurement cannot be performed
- Invalid or non-public URL provided — validation error returned
- URL exceeds maxLength of 2048 characters — schema validation failure
- Target server blocks automated probes — connection may time out or be refused
- CSS selector matches no element — first matching element used as fallback or error returned

## How this service works

Prüft am Objekt skript den Befund Verbindungsaufbauzeit.

## Output

Returns a performance finding (Befund) indicating the measured connection setup time (Verbindungsaufbauzeit) for the specified script resource, including timing metrics for the TCP/TLS handshake phase of the network request.
