# IP-to-ASN Change Watch

> IP-to-ASN Change Watch is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Monitors an IP address's ASN mapping and reports whether it has changed since the last check, including which fields changed and their before/after values.

## Facts

- Endpoint: GET https://intel.rallylive.ca/watch/ip/asn
- Price: $0.02/call
- Payment: x402

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 ip-to-asn-change-watch-aecb76aa
```

Example prompt: Keep an eye on 8.8.8.8 for me — check its ASN mapping and tell me if anything has changed since the last time you looked, including exactly which fields are different and what they were before.

## When to prefer this

Use this endpoint when you need to detect changes in an IP's ASN mapping over time rather than just performing a one-time lookup. It is ideal for scheduled monitoring workflows where you want to be notified of BGP routing changes, ISP migrations, or network reassignments without maintaining your own state — the service stores the last result for 90 days and handles the diff computation for you.

## Known failure modes

- IP address not provided or malformed — query parameter missing or invalid format
- No previous result exists for the IP (first call returns current data with changed=false or null diff)
- Stored result has expired beyond the 90-day window — comparison unavailable
- Payment failure via x402 — endpoint returns 402 if USDC payment is not included
- Network or upstream ASN data source unavailable — may return error or stale data

## How this service works

Change watch for ip to asn: runs the check and compares it with the result from your previous call for the same ip (kept 90 days), returning the current answer, changed true/false, exactly which fields changed with before/after values, and when it was last seen. Call it on a schedule to be told when ip to asn lookup changes. $0.01 per check.

## Output

Returns the current IP-to-ASN mapping, a boolean 'changed' flag indicating whether the result differs from the previous call for the same IP (stored up to 90 days), a list of exactly which fields changed with before and after values, and a timestamp of when the IP was last seen.
