# is-port-123-open-bulk

> is-port-123-open-bulk is a paid API for AI agents from ip.intel.rallylive.ca, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-10).

Checks whether port 123 (NTP) is open on up to 20 hosts in a single concurrent batch call, returning per-item results in input order with error fields and a failure count.

## Facts

- Endpoint: GET https://ip.intel.rallylive.ca/bulk/ip/port/123?utm_source=zero.xyz
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-10
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/is-port-123-open-bulk-ad199a0a
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_Q_H05FWYUv9dcevHU3akl

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-123-open-bulk-ad199a0a
```

Example prompt: Check whether port 123 is open on these hosts: 203.0.113.1, 198.51.100.5, 192.0.2.10, 10.0.0.1, and 172.16.0.2 — give me results for all of them in one go.

## When to prefer this

Use this endpoint when you need to check port 123 (NTP) open/closed status on multiple hosts (2–20) simultaneously and want concurrent processing with ordered, per-item results rather than making sequential single-host calls. Prefer this over the single-host endpoint whenever you hold a list of IPs or hostnames to audit in bulk, saving latency and cost per host checked.

## Known failure modes

- Exceeding the 20-host limit per call returns an error or truncated results
- Invalid or unresolvable hostnames produce per-item errors in the response
- Network timeouts on individual hosts populate the per-item error field without failing the whole batch
- Unpaid or failed x402 payment results in a 402 Payment Required response with no data
- Firewall rules on the probe infrastructure may cause false negatives for certain IP ranges

## How this service works

Bulk is port 123 open: up to 20 hosts in one call, processed concurrently, results in input order with a per-item error field and a failure count. Same answer per item as the single endpoint. Batch enrichment for agents that hold a list. $0.10 per batch.

## Output

An ordered array of per-host results matching the input list, each containing whether port 123 is open or closed on that host, a per-item error field if the probe failed, and an overall failure count for the batch.
