# hostname-to-ips-watch

> hostname-to-ips-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 a hostname's resolved IP addresses and hosting attribution for changes, returning a diff of what changed since the last check.

## Facts

- Endpoint: GET https://intel.rallylive.ca/watch/host/ips
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

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 hostname-to-ips-watch-c6e6f518
```

Example prompt: Keep an eye on example.com for me — check every day and let me know if its resolved IP addresses or hosting provider ever change from what you saw last time.

## When to prefer this

Choose this endpoint when you need to detect changes in a hostname's IP resolution or hosting attribution over time without maintaining your own state — it handles snapshot storage for 90 days and returns precise before/after diffs. Prefer it over a plain hostname-to-IPs lookup when your use case is scheduled monitoring, drift detection, or infrastructure change alerting rather than a one-off resolution.

## Known failure modes

- Domain not resolvable — hostname does not exist or DNS lookup fails
- No prior snapshot available — first call returns current data with changed=false or null baseline
- Snapshot expired — previous result older than 90 days is purged, baseline resets
- Rate limit or payment failure — x402 payment not processed, call rejected
- Malformed hostname input — invalid domain format returns error

## How this service works

Change watch for hostname to ips: runs the check and compares it with the result from your previous call for the same domain (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 hostname to ips with hosting attribution changes. $0.01 per check.

## Output

Returns the current resolved IP addresses and hosting attribution for the hostname, a boolean indicating whether anything changed since the last call for that domain (stored for 90 days), a detailed diff of exactly which fields changed with before and after values, and a timestamp of when the result was last seen.
