# is-ip-starlink-watch

> is-ip-starlink-watch is a paid API for AI agents from ip.intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-12).

Monitors whether a given IP address belongs to Starlink's network, returning a change-diff with before/after values and a changed flag compared to the previous call.

## 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 is-ip-starlink-watch-644a7de2
```

Example prompt: Watch the IP 203.0.113.45 for me and let me know if its Starlink status changes — compare it against the last time you checked and show me what flipped.

## When to prefer this

Use this endpoint when you need to detect changes in Starlink attribution for an IP over time, rather than a one-shot lookup. Ideal for scheduled polling workflows, alerting pipelines, or security monitoring where knowing that something changed (and what the before/after state was) is more valuable than knowing the current state alone. Prefer this over a plain Starlink check when you need diff semantics, not just a current answer.

## Known failure modes

- IP address not provided or malformed — may return an error or no result
- No previous result stored (first call for this IP) — 'changed' may be null or false by default
- IP belongs to a Starlink-adjacent network not in the detection dataset — false negative
- Result cache expired after 90 days — comparison baseline lost
- Payment not processed (x402) — request rejected before check runs

## How this service works

Change watch for is ip starlink: runs the check, compares it with the result from your previous call for the same ip (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.

## Output

Returns the current is-Starlink boolean result, a 'changed' true/false flag indicating whether the answer differs from the previous call for the same IP, a list of fields that changed with before/after values, and a timestamp of when the IP was last seen. Previous result is stored for up to 90 days.
