How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with a schema identifier ('delx/util-ip-v4-private-check/v1') and a boolean field 'is_private' indicating whether the provided IPv4 address falls within a private (RFC 1918 or loopback) address range.
Example use cases
Filter internal IPs from logs
“I have an IP address from our server logs — 172.16.4.23 — can you tell me if it's a private IP that I should filter out before sending logs to our analytics service?”
Security check on incoming request IP
“An incoming request came from 203.0.113.45 — is that a private or public IPv4 address? I need to know before deciding whether to apply our internal trust policy.”
Validate user-submitted IP in form
“A user submitted 192.168.0.100 as their server's IP address in our onboarding form — can you check whether that's a private IP so I can warn them it won't be reachable from the internet?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/ip-v4-private-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs a fast, cheap, verifiable single-call check of whether an IPv4 address is private — especially in pay-per-use agent pipelines where no API key signup is desired and payment is handled via x402 (USDC on Base or Solana). Prefer this over rolling your own regex when auditability and micropayment-based access are required.
Side effects
- Invalid or malformed IPv4 string returns an error response
- Non-IPv4 input (e.g. IPv6 or hostname) may not be supported
- Payment failure (insufficient USDC balance) blocks the call under x402 protocol
- Network timeout or service unavailability
