## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-ipv4-private-address-validator-cd26b09b -d '<json body>'
```

Example prompt: Can you check if 10.0.0.1 is a private IP address — I need to know if it's a local network address or something publicly routable.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call check of whether an IPv4 address is private (RFC 1918) with no signup or API key required — ideal for agent workflows that encounter arbitrary IP addresses and need to classify them quickly and cheaply at $0.001 per call via USDC on Base or Solana.

## Known failure modes

- Malformed or non-IPv4 input string may return valid=false
- IPv6 addresses are not handled by this endpoint
- Empty or missing 'ip' field may result in an error response
- Payment failure via x402 protocol blocks the request

## 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 the input IP address, a boolean 'valid' field indicating whether it's a well-formed IPv4 address, a boolean 'private' field indicating whether it falls within an RFC 1918 private range, and a schema identifier string.
