How this service works
Bulk is port 513 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 whether port 513 is open or closed, a per-item error field if the check failed, and a summary failure count across the batch.
Example use cases
Security audit for exposed rlogin ports
“I have a list of 15 public-facing servers — can you check all of them at once to see which ones have TCP port 513 (rlogin) open? I need the results in the same order I give them to you, with any errors noted.”
Pre-deployment infrastructure scan
“Before we go live, scan these 20 staging hosts for open port 513 in one shot and tell me how many failed or are unreachable: host1.example.com through host20.example.com.”
Compliance check for legacy protocol exposure
“Our compliance team needs to know if any of these 12 IP addresses still have port 513 open — can you run the batch check and give me a count of failures alongside each result?”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/bulk/ip/port/513?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to check port 513 status across multiple hosts simultaneously and want to avoid making N sequential single-host calls. It processes up to 20 hosts concurrently, returns results in input order, and includes per-item error handling — ideal for batch enrichment pipelines, security audits, or infrastructure scans where you already hold a list of targets.
Side effects
- Batch exceeds 20 hosts — request rejected or truncated
- Individual host unreachable — per-item error field populated, counted in failure total
- Invalid hostname or IP format in input — per-item error returned
- Network timeout from Cloudflare edge to target host — item marked as error
- Payment not fulfilled (x402) — request blocked before processing
