How this service works
Metered web utilities for developers and AI agents: browser screenshot and PDF, crypto, DNS and net tools. Pay per request with x402 (USDC on Base) or prepaid API keys.
Output
Returns a JSON object with ok status, the utility name, a requestId for tracking, chargedCredits count, and the computed CIDR details including network address, broadcast address, netmask, IP range start/end, and total/usable host counts.
Example use cases
Subnet planning for cloud VPC
“I'm setting up a VPC and need to know how many usable IPs are in 172.16.0.0/20 — can you give me the full subnet breakdown including network address, broadcast, and host range?”
Validate firewall rule CIDR
“Before I add this to our firewall rules, can you parse 192.168.100.128/26 and confirm the exact IP range it covers so I know it won't overlap with anything unexpected?”
Network troubleshooting IP lookup
“We got an alert for 10.4.32.0/19 — what's the full range of IPs that covers, and what's the broadcast address? Need to narrow down which machines might be affected.”
Technical details
Endpoint
POSThttps://util.beauty/v1/net/cidrWhen to prefer
Choose this endpoint when you need quick, metered, pay-per-call CIDR subnet calculations without standing up your own networking library — especially useful in AI agent workflows that need on-demand network math paid via USDC on Base (x402) or a prepaid API key. Ideal for one-off lookups in automation pipelines rather than bulk subnet processing.
Side effects
- Invalid CIDR notation format returns an error response
- IPv6 CIDR may not be supported — only IPv4 input confirmed
- Missing or malformed request body returns 400-level error
- Payment failure via x402 if USDC balance is insufficient
- Rate limiting or quota exhaustion on prepaid API key
