# SignalDesk AI IPv4 Info

> SignalDesk AI IPv4 Info is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-13).

Classifies an IPv4 address and returns its integer representation along with routing/classification labels (e.g. private, loopback, public).

## Facts

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 signaldesk-ai-ipv4-info-4bda7479 -d '<json body>'
```

Example prompt: Can you check whether 203.0.113.42 is a public or private IPv4 address and give me its classification?

## When to prefer this

Choose this endpoint when you need a lightweight, paid-but-cheap ($0.001 USDC) classification of a single IPv4 address — especially when you need both the integer representation and routing classification in one call. Prefer this over free GeoIP tools when you specifically need private/reserved/loopback classification rather than geolocation data.

## Known failure modes

- Invalid or malformed IPv4 address input returns an error
- IPv6 addresses are not supported (maxLength:15 field implies IPv4 only)
- Ambiguous IPs near reserved boundaries may trigger a warning rather than a definitive classification
- Payment failure (x402) blocks the call entirely

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

Returns a JSON object with the original IP string, its 32-bit integer equivalent, one or more classification labels (e.g. 'private', 'loopback', 'public', 'reserved'), and an optional warning note about the absence of a classification not guaranteeing public routability.
