How this service works
Bulk is port 139 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 order, each containing the open/closed status of port 139, a per-item error field indicating any connectivity or resolution failures, and an overall failure count summarizing how many hosts could not be checked.
Example use cases
Security audit of server fleet
“I have a list of 15 production server IPs and I need to know which ones have port 139 open — can you check them all at once and tell me which are exposing NetBIOS?”
Pre-deployment network hardening check
“Before we go live, scan these 12 host IPs for open port 139 so we can confirm none of them are accidentally exposing SMB to the network.”
Incident response triage across subnet
“We had a security alert — can you quickly check all 20 of these IPs from our internal subnet to see which ones have port 139 reachable right now?”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/bulk/ip/port/139?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have a list of multiple hosts (up to 20) and need to check port 139 status across all of them efficiently in a single API call rather than making individual requests. Prefer this over the single-host endpoint whenever batch throughput matters — it runs probes concurrently and returns results in input order, making it ideal for fleet audits, subnet sweeps, or pre-deployment security checks. Choose this when you need structured per-item error reporting alongside results.
Side effects
- Batch exceeds 20 hosts — only up to 20 hosts supported per call
- Individual host unreachable or DNS resolution failure — per-item error field populated, failure count incremented
- Invalid IP address or hostname format in input — per-item error returned
- Payment not included or insufficient — HTTP 402 response blocking request
- Network timeout on concurrent port probe — per-item error with timeout detail
