# is-port-389-open-bulk

> is-port-389-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 2026-10-11).

Checks whether TCP port 389 (LDAP) is open on up to 20 hosts concurrently in a single API call, returning ordered results with per-item error fields and a failure count.

## Facts

- Endpoint: GET https://ip.intel.rallylive.ca/bulk/ip/port/389?utm_source=zero.xyz
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-11
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/is-port-389-open-bulk-d747c3c7
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_-j1-AorMzeHz9gTO25RXM

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-389-open-bulk-d747c3c7
```

Example prompt: Can you check whether port 389 is open on these servers: 192.168.1.10, 192.168.1.20, 10.0.0.5, ldap.mycompany.com, and dc1.mycompany.com — all in one batch?

## When to prefer this

Choose this endpoint when you need to check port 389 status on multiple hosts (2–20) simultaneously and want results in a single API call rather than making individual requests per host. It is ideal for fleet audits, security scans, and pre-deployment checks where latency savings from concurrent probing matter. Use the single-host endpoint instead if you only need to check one host at a time.

## Known failure modes

- Batch exceeds 20 hosts — request rejected
- Individual host unreachable or DNS resolution failure — per-item error field populated
- Payment not provided or invalid x402 payment — request rejected
- Host actively blocks connection attempts — may return closed even if port is open
- Network timeout per host — reported as per-item error

## How this service works

Bulk is port 389 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 results (one per input host) each containing the open/closed status of port 389, a per-item error field indicating any connection failure, and a top-level failure count summarizing how many hosts could not be reached or checked.
