## 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 is-ip-comcast-watch-c997b2ce
```

Example prompt: Watch this IP address for me and tell me if its Comcast classification changes — let me know the current status, whether anything is different from last time, and what exactly changed.

## When to prefer this

Use this endpoint when you need to detect changes in Comcast ISP classification for a specific IP over time, rather than just a one-shot lookup. It is ideal for scheduled monitoring workflows where you want to be alerted to drift, such as when a server or customer IP migrates away from or onto Comcast's network. Prefer this over the non-watch variant when change detection and before/after diffing matter to your use case.

## Known failure modes

- Missing or invalid IP address in query params returns an error
- IP not previously checked means no diff data is available on first call
- Results older than 90 days are purged, resetting the comparison baseline
- Network timeout from Cloudflare edge may cause transient failures
- Private or reserved IP ranges may return undefined or null results

## How this service works

Change watch for is ip comcast: 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 boolean answer for whether the IP belongs to Comcast, a 'changed' true/false flag, a diff of any fields that changed with before/after values, and a timestamp of when the IP was last seen. Results from prior calls are retained for 90 days for comparison.
