How this service works
Bulk is port 19 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 order, each containing the host identifier, a boolean indicating whether port 19 is open, a per-item error field (null on success or an error message on failure), and an overall failure count summarizing how many hosts could not be checked.
Example use cases
Security audit for Chargen exposure
“I need to audit our infrastructure for exposed Chargen services — can you check if port 19 is open on these 12 hosts: 10.0.0.1, 10.0.0.2, 10.0.0.3, 10.0.0.4, 10.0.0.5, 10.0.0.6, 10.0.0.7, 10.0.0.8, 10.0.0.9, 10.0.0.10, 10.0.0.11, 10.0.0.12?”
Detect amplification attack vectors
“I'm investigating potential DDoS amplification risks — check these 20 IP addresses for open port 19 and let me know which ones have Chargen running and if any checks failed.”
Pre-deployment network compliance check
“Before we go live, I need to confirm none of these 8 new server IPs have port 19 accidentally open — can you batch-check them and give me a clean pass/fail for each one?”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/bulk/ip/port/19?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have a list of 2–20 hosts and need to check port 19 (Chargen) status for all of them efficiently in a single API call rather than making separate single-host requests. Ideal for batch enrichment pipelines, security audits, compliance checks, or agent workflows that accumulate a list of IPs and need concurrent port scanning with ordered, structured results and error isolation per item.
Side effects
- Host unreachable or DNS resolution failure — per-item error field populated, failure count incremented
- Timeout on connection attempt — item marked as error rather than closed
- Input list exceeds 20 hosts — request rejected or truncated
- Malformed host identifier in input — per-item error returned for that entry
- Network-level firewall blocking the probe — port may appear closed even if open
