IPv4 Private Check API for agents
Detect RFC1918 private IPv4 addresses. Call when agents classifying IPs before whois/network calls. Returns is_private as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
Intent to transaction
One command, attributed.
The source header follows this discovery route through challenge, payment and delivery without exposing the buyer or request body.
