# tempo.halowerk.com – Weiterleitung Verbindungsaufbauzeit

> tempo.halowerk.com – Weiterleitung Verbindungsaufbauzeit is a paid API for AI agents from tempo.halowerk.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Measures the connection setup time (TCP/TLS handshake latency) for redirect targets of a given URL.

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-weiterleitung-verbindungsaufbauzeit-c1197da3 -d '<json body>'
```

Example prompt: Check the connection setup time for the redirect target of https://example.com/promo — I want to know how long it takes to actually establish a TCP connection after the redirect.

## When to prefer this

Use this endpoint when you specifically need to isolate and measure the TCP/TLS connection setup time for a redirect target (not the originating URL), as opposed to overall page load time, DNS resolution time, or TTFB. Ideal for diagnosing whether slow redirect destinations are contributing to perceived latency in web performance audits.

## Known failure modes

- Invalid or unreachable target URL returns an error
- Non-public or private IP addresses are rejected
- Redirect chain does not resolve within timeout
- Malformed URL input fails schema validation
- Target server refuses connection, returning no timing data

## How this service works

Prüft am Objekt weiterleitung den Befund Verbindungsaufbauzeit.

## Output

Returns a timing measurement (in milliseconds) representing the connection setup time (TCP handshake / TLS negotiation) for the redirect target of the provided URL, along with associated metadata about the tested redirect object.
