How this service works
Detect private/loopback IPv4. Call when you block private egress targets in agent allowlists. Returns valid and private flags for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
Returns a JSON object with a 'valid' boolean indicating whether the input is a well-formed IPv4 address, and a 'private' boolean indicating whether it falls within private or loopback ranges (RFC 1918, 127.x, etc.). No external network calls are made; classification is done locally.
Example use cases
SSRF prevention in agent pipelines
“I have an agent that makes HTTP requests to user-supplied URLs — before each request, check whether the resolved IP 10.0.0.1 is a private IPv4 address so I can block it and prevent server-side request forgery.”
Egress allowlist enforcement
“My workflow needs to call an external API at 172.16.4.200 — can you verify whether that IP falls in a private range before I let the agent proceed?”
User-submitted IP validation
“A user submitted the IP 127.0.0.1 as a webhook destination — check if it's a loopback or private address so I can reject it and warn them it's not a valid public target.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/ipv4-privateWhen to prefer
Choose this endpoint when you need a fast, cheap, stateless check for private/loopback IPv4 ranges — especially in security-sensitive agent pipelines guarding against SSRF or enforcing egress allowlists. Prefer it over full IP geolocation or threat-intel APIs when you only need the private/public classification without external lookups or retained data.
Side effects
- Malformed or non-IPv4 input may return valid:false with no private classification
- IPv6 addresses are not supported and will likely return invalid
- Empty or missing 'ip' field may cause a 400-level error
- Payment failure (x402) prevents the call from completing
