# is-ip-alibaba

> is-ip-alibaba is a paid API for AI agents from ip.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Checks whether a given IPv4 address is announced by Alibaba's autonomous systems by resolving its origin ASN via Team Cymru DNS and comparing against Alibaba's known ASNs (AS45102, AS37963, AS24429).

## Facts

- Endpoint: GET https://ip.intel.rallylive.ca/ip/is/alibaba?utm_source=zero.xyz
- Price: $0.01/call

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 is-ip-alibaba-cb459f3e
```

Example prompt: Can you check if the IP address 47.252.100.1 belongs to Alibaba's cloud network — I need to know the ASN and whether to flag it in my fraud scoring system.

## When to prefer this

Choose this endpoint when you specifically need to determine if an IP belongs to Alibaba's cloud infrastructure (AS45102, AS37963, AS24429) with authoritative ASN-level resolution via Team Cymru DNS. It is purpose-built for Alibaba detection with a flat $0.01 per-call price, making it ideal for high-volume fraud scoring, allow/block-listing, and cloud provider attribution workflows where Alibaba-specific ASN data is required.

## Known failure modes

- Invalid or malformed IPv4 address input returns an error
- Private or reserved IP addresses (RFC1918) may not resolve to a public ASN
- Team Cymru DNS resolution failures may cause lookup timeouts
- IP addresses not yet in BGP routing tables return no ASN data
- Payment failure (insufficient USDC balance) blocks the request

## How this service works

Is this IPv4 address announced by alibaba? Resolves the address to its origin ASN (Team Cymru DNS) and compares with alibaba's known autonomous systems (AS45102, AS37963, AS24429), returning yes/no with the ASN, prefix and network name. Fraud scoring, allow-listing and infrastructure mapping. $0.01 per lookup.

## Output

Returns a yes/no answer indicating whether the IPv4 address belongs to Alibaba's autonomous systems, along with the resolved ASN number, the IP prefix/subnet it falls under, and the network name associated with that ASN.
