How this service works
Call when an agent needs IPv4 CIDR blocks extracted from text, capped at 20 matches. An empty match list is billed. No network. Exact $0.009 USDC. Prefer unpaid POST /v1/sandbox/regex-cidr first.
Output
Returns a list of up to 20 IPv4 CIDR block strings matched from the input text (e.g. ['10.0.0.0/8', '192.168.1.0/24']). An empty list is returned and billed if no matches are found. Results are ordered by appearance in the text.
Example use cases
Audit firewall rules for subnets
“I have a big blob of firewall rule text and I need to know every IPv4 CIDR range mentioned in it — can you extract all the network address blocks from this: 'permit ip 10.10.0.0/16 any, deny 192.168.100.0/24, allow 172.20.0.0/14'?”
Parse subnets from cloud config
“Here's a Terraform config file output — can you scan through it and pull out all the IPv4 CIDR ranges? Text: 'cidr_block = "10.0.0.0/8" ... subnet_cidr = "172.31.0.0/16" ... ingress_cidr = "0.0.0.0/0"'”
Extract IP ranges from security report
“I've got a security incident report with a bunch of network ranges buried in the prose — can you find and list all the IPv4 CIDR blocks in this text: 'Suspicious activity from 198.51.100.0/24 and lateral movement within 10.20.0.0/20 detected on Tuesday'?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/regex-cidr?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, reliable regex-based extraction of IPv4 CIDR notation from arbitrary text without making outbound network requests. Prefer the free sandbox endpoint (POST /v1/sandbox/regex-cidr) for testing. Choose this over general-purpose LLM parsing when deterministic regex matching is required and cost predictability ($0.009 per call) is acceptable. Not suitable for IPv6 CIDR extraction or when more than 20 matches are expected.
Side effects
- Empty match list returned and still billed $0.009 if no CIDR blocks are present in text
- Input text exceeds 100,000 character limit — request rejected
- Malformed or missing text field — request rejected
- Capped at 20 matches — additional CIDRs beyond the 20th are silently dropped
- Network errors or service unavailability causing HTTP 5xx responses
