# tempo.halowerk.com DNS Resolution Time Check for Documents

> tempo.halowerk.com DNS Resolution Time Check for Documents 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 and reports the DNS resolution time for a given document URL or domain, returning timing performance data.

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-dns-resolution-time-check-for-documents-fbea2ae5 -d '<json body>'
```

Example prompt: Can you check how long DNS resolution takes for https://www.example.com and tell me the timing result?

## When to prefer this

Use this endpoint when you specifically need DNS resolution timing data for a document or domain as part of a web performance audit. It is ideal for diagnosing slow page loads where DNS lookup is suspected as the bottleneck, or for benchmarking DNS performance across different domains. Prefer this over general uptime monitors when the metric needed is specifically DNS resolution latency rather than overall response time or page render speed.

## Known failure modes

- Invalid or non-public URL/domain returns a validation error
- Unreachable or non-existent domain may cause a lookup failure or timeout
- Malformed input schema (e.g. empty ziel field) returns a 400-level error
- Private/internal IP addresses or localhost URLs may be rejected
- CSS selector pointing to no matching element may fall back to first result or error

## How this service works

Prüft am Objekt dokument den Befund DNS-Auflösungszeit.

## Output

Returns a performance finding object containing the measured DNS resolution time for the specified document URL or domain, indicating how long DNS lookup takes in milliseconds or similar timing units.
