# Vokko Domain Host Probe

> Vokko Domain Host Probe is a paid API for AI agents from www.vokko.eu, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

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 vokko-domain-host-probe-68326b4f
```

Example prompt: Can you probe the host for example.com and tell me if it's reachable — a live re-probe is fine, I want fresh results.

## When to prefer this

Use this endpoint when you need to verify whether a specific domain/host is reachable or resolve its DNS status, especially when a cached result is acceptable (free) or a live re-probe is needed ($0.02). Prefer this over general DNS APIs when you want a simple pass/fail host probe with optional caching semantics.

## Known failure modes

- Domain does not exist or cannot be resolved — returns error or empty result
- Network timeout during live re-probe — may return stale cached data or error
- Invalid domain format provided in path parameter — likely a 4xx client error
- Rate limiting or payment failure for paid live probe — may block request

## How this service works

Live re-probe of allbirds.com. Cached GET without refresh is free.

## Output

Returns host probe data for the requested domain, including reachability status and DNS resolution details. Cached GET responses are free; a live re-probe costs $0.02 USDC. The response indicates whether the host is up and provides relevant connectivity metadata.
