# is-port-179-open-watch

> is-port-179-open-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 2026-10-13).

Change-detection watch for TCP port 179 (BGP) availability: runs the check, compares to the previous result (stored 90 days), and returns current status plus a changed flag with before/after diff.

## Facts

- Endpoint: GET https://ip.intel.rallylive.ca/watch/ip/port/179?utm_source=zero.xyz
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-13

- Tags: x402
- Canonical page: https://www.zero.xyz/c/is-port-179-open-watch-c0edeffa
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_5KE8VhxfxAeM6szy8BtGj

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 is-port-179-open-watch-c0edeffa
```

Example prompt: Keep an eye on whether TCP port 179 (BGP) is open on router.example.com — check it now and let me know if anything has changed since the last time you looked.

## When to prefer this

Use this endpoint when you need change-detection semantics for port 179 specifically — it stores prior state for 90 days so you don't have to manage your own baseline. Prefer this over the plain is-port-179-open endpoint when you want to detect transitions (open→closed or vice versa) and trigger alerts. Choose the bulk variant if checking multiple hosts simultaneously.

## Known failure modes

- Host unreachable or DNS resolution failure — port reported as closed/error
- No previous result stored (first call for this host) — changed flag may be null or false by default
- Host actively blocks probes — false negative (port appears closed when filtered)
- 90-day history expiry — previous result no longer available for comparison
- Payment failure — $0.02 USDC not satisfied, request rejected

## How this service works

Change watch for is port 179 open: runs the check, compares it with the result from your previous call for the same host (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 open/closed status of TCP port 179, a boolean 'changed' flag, a before/after diff of any fields that changed, and the timestamp of when the status was last seen. Enables alerting workflows when state transitions occur.
