How this service works
Bulk is port 137 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 the port 137 open/closed status (same as the single-host endpoint), a per-item error field indicating any probe failure, and an overall failure count for the batch.
Example use cases
NetBIOS exposure audit across subnet
“I need to audit our office network — can you check if port 137 is open on all 18 of these internal IP addresses and tell me which ones are exposing NetBIOS? Here's the list: 10.10.0.1 through 10.10.0.18.”
Pre-deployment security scan for new servers
“Before we take these 12 new cloud servers live, can you scan all of them for open port 137 and flag any that have NetBIOS name service exposed? I'll paste the IP list: 203.0.113.10, 203.0.113.11, 203.0.113.12, 203.0.113.13, 203.0.113.14, 203.0.113.15, 203.0.113.20, 203.0.113.21, 203.0.113.22, 203.0.113.30, 203.0.113.31, 203.0.113.32.”
Threat intelligence enrichment for suspicious IPs
“I've got a batch of 20 suspicious IPs from our firewall logs — run a port 137 check on all of them at once and tell me which ones have NetBIOS open, and flag any that errored out.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/bulk/ip/port/137?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have a list of 2–20 hosts and need to check port 137 status across all of them efficiently in a single call. It is superior to calling the single-host endpoint repeatedly because results are processed concurrently and returned in input order with per-item error handling — ideal for batch enrichment pipelines, security audits, or infrastructure scans. Choose this over the single endpoint whenever you hold a list.
Side effects
- Host unreachable or times out — reflected in per-item error field with failure incremented in count
- More than 20 hosts submitted — batch limit exceeded, likely 400 error
- Invalid hostname or IP format — per-item error returned for that entry
- Network-level block prevents probe — may return false-closed with error flag
- Payment not processed — x402 payment required error before results returned
