## 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-cidr-contains-check-fd65f402 -d '<json body>'
```

Example prompt: Check whether the IP address 203.0.113.45 is contained within the CIDR block 203.0.113.0/24.

## When to prefer this

Use this endpoint when you need a quick, pay-per-use CIDR containment check with no signup or subscription required, paid via USDC on Base or Solana. Ideal for AI agents that need on-demand IP range validation without managing API keys or monthly plans. Prefer this over self-hosted solutions when you want verifiable, metered delivery at $0.001 per call.

## Known failure modes

- Invalid IP address format — malformed input causes rejection
- Invalid CIDR notation — incorrect subnet mask or prefix length
- Missing required body fields — request fails if IP or CIDR is omitted
- Payment failure — x402 USDC payment not processed correctly, returns 402
- Network timeout — service unavailable, returns 5xx error

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output
