# SignalDesk AI – ASN Lookup

> SignalDesk AI – ASN Lookup is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-13).

Looks up detailed information about an Autonomous System Number (ASN), including the holder name, block assignment, and announcement status, sourced from RIPEstat.

## Facts

- Endpoint: GET https://x402-agent.kariguetoazul.workers.dev/api/security/asn?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_evxbaHOFbmoB7OL9jcUxc

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-asn-lookup-c477f9f2
```

Example prompt: Look up ASN 15169 for me — I want to know who holds it, what IP block it belongs to, and whether it's currently announced.

## When to prefer this

Choose this endpoint when you need structured, evidence-backed ASN metadata (holder, block, announcement status) sourced from RIPEstat, especially in automated agent workflows that require micropayment-gated, reliable lookups without managing your own RIPEstat integration. It is ideal for enriching network logs, security investigations, or BGP analysis pipelines at $0.002 per call.

## Known failure modes

- Invalid or out-of-range ASN (must be 1–4294967295) returns an error
- ASN not found or not yet assigned returns empty or null holder data
- RIPEstat upstream unavailable causes fetch failure
- Stale cached data may be returned if the upstream source is slow to refresh

## 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 ASN number and type, the holder name (e.g. 'GOOGLE - Google LLC'), the block resource range with name and description, whether the AS is announced, and source metadata including the RIPEstat provider URL and cache timestamps.
