How this service works
Bulk is port 515 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 515 is open, a per-item error field (populated if the probe failed), and a summary failure count for the batch.
Example use cases
Security audit for exposed printer ports
“I need to check whether port 515 is open on all 18 of our public-facing servers — here's the list of IPs. Flag any that have the LPD printer port exposed so we can close them down.”
Fleet readiness check before print job rollout
“Before we push the print job queue, can you verify that port 515 is open and reachable on these 12 print server hosts? I need a pass/fail for each one.”
Post-firewall-change verification
“We just updated the firewall rules — can you batch-check whether port 515 is still open on these 20 hosts and tell me if any of them are now unreachable?”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/bulk/ip/port/515?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to check port 515 status across multiple hosts (up to 20) in a single API call rather than making sequential single-host requests. It processes hosts concurrently so total latency is near that of a single check, making it ideal for fleet audits, pre-deployment verification, or security scans over a list of IPs. Prefer the single endpoint when you only have one host to check.
Side effects
- More than 20 hosts submitted — batch size limit exceeded
- Unreachable or invalid host causes per-item error field to be populated rather than open/closed status
- Network timeout on a specific host results in that item marked as error without affecting others
- Payment not attached or insufficient — x402 payment required error returned
- All hosts unreachable returns full failure count equal to batch size
