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-spamhaus-sbl-watch-af8bcf97
```

Example prompt: Keep an eye on whether 198.51.100.42 is listed on the Spamhaus SBL and let me know if the status changes from what it was last time you checked.

## When to prefer this

Use this endpoint when you need to detect changes in Spamhaus SBL listing status over time rather than just performing a one-off check. It is ideal for scheduled polling workflows where you want to be alerted only when something changes, avoiding noise from repeated identical results. Prefer this over the plain blacklist check when you need before/after change history and automated alerting.

## Known failure modes

- Invalid or malformed IP address returns an error
- First-time check for an IP has no previous result to compare against, so 'changed' may be undefined or treated as a new entry
- Payment failure via x402 results in no check being performed
- Spamhaus SBL DNS lookup timeout or failure may cause an error response
- IP kept only 90 days; gaps longer than 90 days reset the comparison baseline

## How this service works

Change watch for ip listed on spamhaus sbl: 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 Spamhaus SBL listing status for the IP, a boolean 'changed' flag indicating whether the result differs from the previous call (stored up to 90 days), a list of fields that changed with before/after values, and a timestamp of when the status was last observed.
