# CoCo CIDR Calculator

> CoCo CIDR Calculator is a paid API for AI agents from cocoeatsai.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-19).

Computes detailed network information for a given IP address or CIDR block, including subnet mask, broadcast address, host range, and address counts.

## Facts

- Endpoint: GET https://cocoeatsai.com/area4/agent/tools/cidr?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 coco-cidr-calculator-7a89a02b
```

Example prompt: Can you calculate the subnet details for 10.0.0.0/24 — I need the network address, broadcast, first and last host, netmask, and how many usable hosts there are?

## When to prefer this

Choose this endpoint when you need quick, offline-computable CIDR/subnet decomposition without hitting a heavy network library or setting up your own tooling. It is ideal for agents doing network planning, infrastructure configuration, or IP range validation where a single structured JSON result covering all key subnet fields is needed in one call.

## Known failure modes

- Invalid or malformed CIDR notation returns an error or empty response
- Missing 'value' query parameter may return a bad request error
- IPv6 inputs may not be fully supported or may return partial data
- Prefix lengths out of valid range (e.g. /33 for IPv4) may cause computation errors

## Output

Returns a JSON object with full subnet details: network address, prefix length, netmask, broadcast address, first and last usable host IPs, number of usable hosts, total address count, IP version (4 or 6), and whether the range is a private network.
