SignalDesk AI CIDR Info
x402
SignalDesk AI CIDR Info is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-13).
Computes subnet details for an IPv4 CIDR block, returning network address, broadcast, mask, usable host range, and address counts.

How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
Returns a JSON object with the subnet mask (dotted-decimal), prefix length (integer), network address, broadcast address, first usable host IP, last usable host IP, number of usable hosts, and total address count for the given CIDR block.
Example use cases
Subnet planning for cloud VPC
“I'm setting up a VPC and need to know how many usable hosts I get in a 10.0.0.0/20 block — also give me the first host, last host, and broadcast address.”
Network documentation automation
“For our internal network documentation, pull all the subnet details for 172.16.32.0/22 — mask, network address, broadcast, first and last usable host.”
Security audit IP range verification
“I need to verify whether a /27 subnet on 203.0.113.96/27 gives us enough addresses — tell me the total addresses, usable hosts, and the full host range.”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/network/cidr-info?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, deterministic subnet math for a single IPv4 CIDR block — especially in automated infrastructure workflows, network documentation pipelines, or security tooling where you need precise host range, mask, and broadcast details without spinning up a local subnet calculator. It is metered at $0.001 USDC via x402, making it suitable for low-volume programmatic lookups in agent workflows.
Side effects
- Invalid or malformed CIDR string returns an error (e.g. missing prefix, out-of-range prefix length)
- IPv6 CIDRs are not supported — only IPv4
- CIDR string exceeding 18 characters is rejected by schema validation
- Network errors or Cloudflare Worker downtime return HTTP 5xx
- Missing or empty `cidr` field returns a validation error
