## 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-barracuda-watch-a9c2cacf
```

Example prompt: Watch 203.0.113.42 on the Barracuda blacklist and let me know if anything changes from the last time you checked — I want to see whether it's listed now, and whether that's different from before.

## When to prefer this

Choose this endpoint when you need to track changes in an IP's Barracuda blacklist status over time rather than just a one-off lookup. It is ideal for automated monitoring pipelines, alerting workflows, or scheduled jobs where knowing whether the status changed (and what changed) matters more than just the current state.

## Known failure modes

- Invalid or malformed IP address returns an error
- No previous check exists for the IP so 'changed' cannot be computed on first call
- Barracuda service temporarily unavailable causes lookup failure
- Payment not processed results in 402 response
- IP history expired after 90 days resets the comparison baseline

## How this service works

Change watch for ip listed on barracuda: 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 Barracuda blacklist status for the IP, a boolean indicating whether the result changed since the last call, a breakdown of which fields changed with their before and after values, and a timestamp of when the IP was last seen. History is retained for 90 days.
