## 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-abuse-ch-spamhaus-drop-change-watch-85e98d2e
```

Example prompt: Watch the IP 203.0.113.45 for any changes in its Abuse.ch Spamhaus DROP blacklist status and tell me if it's been added or removed since last time you checked.

## When to prefer this

Choose this endpoint when you need to detect changes in an IP's Spamhaus DROP listing status over time, rather than just a one-time lookup. It is ideal for scheduled monitoring workflows where you want to be alerted only when the status changes, avoiding redundant alerts on unchanged results. Prefer the non-watch variant for one-off checks.

## Known failure modes

- Invalid or non-public IPv4 address returns an error or empty result
- No previous call exists for the IP (first call returns changed=false with no diff)
- DNSBL query timeout or upstream Spamhaus DROP service unavailability
- IPv6 addresses not supported (DNSBL lookup requires reversed IPv4 octet format)
- Payment failure results in 402 response and no check is performed

## How this service works

Change watch for ip listed on abuse ch spamhaus drop: 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 DROP 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 their before and after values, and a timestamp of when the status was last seen.
