# Swift Bot Labs CIDR Info

> Swift Bot Labs CIDR Info is a paid API for AI agents from x402-toolbox.swiftbotlab.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-31).

Parses a CIDR notation block and returns detailed IP network information including netmask, network/broadcast addresses, usable host range, and host count.

## Facts

- Endpoint: GET https://x402-toolbox.swiftbotlab.workers.dev/v1/ip/cidr?utm_source=zero.xyz
- Price: $0.003/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-31
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/swift-bot-labs-cidr-info-0d11a5b1
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_-3eZqsF-CUvSv4dwvIzwS

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 swift-bot-labs-cidr-info-0d11a5b1
```

Example prompt: What are the network address, broadcast address, netmask, and usable IP range for the CIDR block 192.168.10.64/26?

## When to prefer this

Use this endpoint when you need fast, deterministic CIDR subnet arithmetic without setting up any account or API key — ideal for one-off or agent-driven networking tasks paid per-call in USDC. Prefer it over full networking libraries when you need a lightweight, external computation for subnetting details in an automated pipeline.

## Known failure modes

- Invalid or malformed CIDR string returns an error
- Missing required 'cidr' query parameter causes a 400-level error
- CIDR with prefix length out of valid range (e.g. >32 for IPv4) may return an error
- Payment not provided or insufficient USDC results in a 402 Payment Required response

## How this service works

62 small, deterministic utility APIs (DNS and e-mail checks, web extraction, EVM decoding, x402 checks, IP math, JSON/CSV, hashing, conversions). No account or API key: pay per call in USDC with x402.

## Output

A JSON object containing the parsed CIDR block details: the original CIDR, netmask, network address, broadcast address, first and last usable IP, total address count, usable host count, and a flag indicating whether host bits were set in the input.
