# is-port-445-open-bulk

> is-port-445-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 445 (SMB/CIFS) is open on up to 20 hosts concurrently in a single batch call, returning results in input order with per-item errors and a failure count.

## Facts

- Endpoint: GET https://ip.intel.rallylive.ca/bulk/ip/port/445?utm_source=zero.xyz
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-11

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_lsvhLhfeI2DFciPQCfcnd

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-445-open-bulk-2dc26a8e
```

Example prompt: Can you check if port 445 is open on these 10 servers all at once: 192.168.1.1, 192.168.1.2, 192.168.1.3, 192.168.1.4, 192.168.1.5, 10.0.0.1, 10.0.0.2, 10.0.0.3, 10.0.0.4, and 10.0.0.5? I need the status for each one and a count of any failures.

## When to prefer this

Use this endpoint when you have a list of 2–20 hosts and need to check port 445 status for all of them efficiently in a single API call rather than making individual requests. It is ideal for infrastructure audits, security scans, or enrichment pipelines where you hold a batch of IPs or hostnames and need concurrent, ordered results with error isolation per host.

## Known failure modes

- Host unreachable or DNS resolution failure — per-item error field populated
- Batch exceeds 20 hosts — request rejected or truncated
- Network timeout from Cloudflare edge to target host — item marked as error
- Invalid host format in input — per-item error
- Payment not provided or insufficient — 402 response blocking the call

## How this service works

Bulk is port 445 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 matching the input host list, where each item contains the host identifier, a boolean or status indicating whether port 445 is open or closed, a per-item error field if the check failed, and an overall failure count summarizing how many hosts could not be probed.
