# ip-listed-on-surbl-multi-watch

> ip-listed-on-surbl-multi-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 an IP address for changes in its SURBL Multi blacklist status, returning current result, change flag, before/after diffs, and last-seen timestamp.

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-listed-on-surbl-multi-watch-7d23011a
```

Example prompt: Keep an eye on whether 192.0.2.45 is listed on SURBL Multi and let me know if its blacklist status changes from what it was last time you checked.

## When to prefer this

Choose this endpoint when you need to detect transitions in an IP's SURBL Multi blacklist status over time rather than just a one-time check. It is ideal for scheduled monitoring workflows, alerting pipelines, and audit trails where knowing what changed (and when) matters more than the raw current value. Use the non-watch sibling endpoint for one-off lookups without history.

## Known failure modes

- IP parameter missing or malformed — query cannot be executed
- No previous result stored (first call) — 'changed' will be false/null with no before values
- Previous result expired beyond 90-day retention — treated as first call
- DNSBL query timeout or SURBL Multi service unavailability — error response
- Invalid IPv4 format provided — lookup fails

## How this service works

Change watch for ip listed on surbl multi: 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 SURBL Multi blacklist result for the IP, a boolean 'changed' flag comparing to the previous stored result (retained 90 days), the specific fields that changed with before and after values, and the timestamp of when the status was last seen.
