# IP Listed on RBL-JP Change Watch

> IP Listed on RBL-JP Change 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 2026-10-13).

Monitors whether an IP address is listed on the RBL-JP blacklist and returns whether the status has changed since the last check, with before/after field diffs.

## 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-listed-on-rbl-jp-change-watch-d796f43f
```

Example prompt: Keep an eye on whether my IP 203.0.113.42 is listed on RBL-JP and let me know if anything changes compared to the last time you checked.

## When to prefer this

Choose this endpoint when you need to detect changes in a specific IP's RBL-JP blacklist status over time rather than just performing a one-off check. It is ideal for scheduled monitoring pipelines, alerting workflows, and audit trails where knowing that the status changed — and exactly what changed — is more important than the raw current value alone.

## Known failure modes

- IP not previously checked — no baseline to compare against, 'changed' may be null or treated as first-seen
- RBL-JP DNS query timeout or failure — may return error or stale result
- Invalid IP address format — request rejected with validation error
- 90-day history expired — previous result no longer available, treated as new baseline
- Payment failure — x402 USDC payment not completed, request blocked

## How this service works

Change watch for ip listed on rbl jp: 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 RBL-JP blacklist status for the IP, a boolean 'changed' flag indicating whether the result differs from the previous call (stored up to 90 days), the specific fields that changed with their before and after values, and the timestamp of when the status was last seen.
