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 a single boolean field 'overlaps' indicating whether the two provided CIDR blocks share any IP address space.
Example use cases
Pre-deployment subnet conflict check
“Before I add 10.20.0.0/16 to our VPC, check whether it overlaps with the existing 10.0.0.0/8 range we already have.”
Multi-tenant IP space validation
“We're onboarding a new customer who says their network is 172.16.5.0/24 — does that clash with our internal 172.16.0.0/20?”
Firewall rule planning
“Does 192.168.100.0/22 overlap with 192.168.102.0/24? I want to make sure my firewall rules won't accidentally double-cover those ranges.”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/network/cidr-overlap?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, single-call computation to determine IP address space conflicts between exactly two CIDR blocks. Ideal for infrastructure automation, network provisioning validation, or security rule checks where a simple true/false overlap result is sufficient and speed matters.
Side effects
- Invalid CIDR notation for either input (malformed string, e.g. missing prefix length) may return an error
- CIDR string exceeding 18 characters will be rejected by schema validation
- Missing required fields 'a' or 'b' will result in a bad request error
- Payment failure or insufficient USDC balance will block execution under x402 protocol
