How this service works
Call when an agent needs whether a string is an IPv6 CIDR prefix. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/check-ip-cidr6 first.
Output
Returns a boolean or structured response indicating whether the provided string is a valid IPv6 CIDR prefix, confirming correct address and prefix-length formatting.
Example use cases
Network configuration input validation
“Before I save this firewall rule, can you verify that '2600:1f18::/36' is actually a valid IPv6 CIDR prefix so I know the configuration is correct?”
User-submitted subnet format check
“A user just entered 'fe80::1/64' as their IPv6 network range in the form — can you tell me if that's a properly formatted IPv6 CIDR prefix?”
Automated network provisioning guard
“I'm about to provision a new VPC with the prefix 'fd00::/8' — can you confirm that's a valid IPv6 CIDR block before I proceed?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-ip-cidr6?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, reliable paid check specifically for IPv6 CIDR prefix validity. Prefer the free sandbox endpoint POST /v1/sandbox/check-ip-cidr6 for testing or cost-sensitive scenarios. Use this paid endpoint when sandbox is unavailable or you need production-grade reliability.
Side effects
- Empty or missing value field returns validation error
- String exceeding 20000 characters may be rejected
- Non-IPv6 strings (e.g. IPv4 CIDR) may return false rather than an error
- Malformed prefix length (e.g. /129 or /abc) returns invalid result
- Network unreachability causes timeout or HTTP error
