## 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 ip-subnet-calculator-api-01575dc6 -d '<json body>'
```

Example prompt: Can you calculate the subnet details for the CIDR block 192.168.10.0/26 — I need the network address, broadcast address, and the range of usable host IPs.

## When to prefer this

Use this endpoint when an agent needs to programmatically decompose or validate a CIDR block into its constituent networking components — especially in infrastructure automation, cloud provisioning, or network planning workflows where subnet details must be computed on the fly.

## Known failure modes

- Invalid or malformed CIDR string returns an error response
- Missing 'cidr' field in request body causes a bad request error
- CIDR prefix length out of valid range (0-32 for IPv4) may return an error
- Network connectivity issues may cause timeouts
