Swift Bot Labs Toolbox – IP CIDR Contains Check
x402
Swift Bot Labs Toolbox – IP CIDR Contains Check is a paid API for AI agents from x402-toolbox.swiftbotlab.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-31).
Checks whether one or more IP addresses fall within one or more CIDR network blocks, returning per-IP match results.

How this service works
62 small, deterministic utility APIs (DNS and e-mail checks, web extraction, EVM decoding, x402 checks, IP math, JSON/CSV, hashing, conversions). No account or API key: pay per call in USDC with x402.
Output
Returns a JSON object with a results array where each entry contains the queried IP, a 'matches' array listing which CIDR blocks contain it, and a boolean 'contained' flag. Also returns arrays of any invalid IPs or CIDRs submitted.
Example use cases
Firewall allowlist enforcement check
“I have a list of IPs from our access logs — 203.0.113.5, 10.4.8.1, and 172.16.0.22 — can you tell me which ones fall inside our internal network ranges 10.0.0.0/8 and 172.16.0.0/12?”
Cloud egress IP whitelisting validation
“We need to verify that all our cloud provider egress IPs (54.239.28.85, 52.94.236.248, 13.32.0.1) are within the known AWS CIDR blocks 54.239.0.0/16 and 52.94.0.0/15 — can you run that check for me?”
Security alert IP geofencing triage
“Flag which of these suspicious IPs — 192.168.1.55, 172.31.200.4, 8.8.4.4, 100.64.0.1 — are actually inside our private RFC 1918 ranges 192.168.0.0/16, 172.16.0.0/12, and 10.0.0.0/8 so I can deprioritize internal false positives.”
Technical details
Endpoint
POSThttps://x402-toolbox.swiftbotlab.workers.dev/v1/ip/contains?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, stateless, server-side check of IP-to-CIDR containment without spinning up networking libraries locally. Ideal for batch membership checks (up to 1000 IPs and CIDRs per call), firewall rule validation, security triage, and allowlist/denylist enforcement. Prefer it over self-hosted solutions when you want no infrastructure overhead and pay-per-call USDC pricing via x402.
Side effects
- Invalid IP address format returns it in invalidIps array rather than erroring
- Invalid CIDR notation returns entry in invalidCidrs array
- Exceeding 1000 IPs or CIDRs may be rejected or truncated
- Malformed request body returns an error response
- Payment failure via x402 results in 402 response before execution
