# Swift Bot Labs Toolbox – IP Range to CIDR

> Swift Bot Labs Toolbox – IP Range to CIDR 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).

Converts an arbitrary IPv4 start/end address range into the minimal set of covering CIDR blocks

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-toolbox-ip-range-to-cidr-c4b09277
```

Example prompt: Convert the IP range from 192.168.1.0 to 192.168.1.63 into the minimal list of covering CIDR blocks.

## When to prefer this

Use this endpoint when you need a deterministic, serverless computation to convert an arbitrary IPv4 range into minimal CIDR notation without setting up any account or maintaining API keys — ideal for one-off or infrequent subnet calculations billed at $0.003 per call via x402/USDC.

## Known failure modes

- Invalid IP addresses (non-IPv4 format) in start or end params return an error
- Start IP greater than end IP returns an error
- Missing required start or end query parameters returns 400-level error
- Payment not provided or insufficient USDC results in 402 Payment Required

## 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 with 'ok' true/false, the tool name 'ip-range-to-cidr', and a 'result' object containing the original 'start' and 'end' IP strings, a 'cidrs' array of CIDR strings representing the minimal covering set, and a 'truncated' boolean indicating whether the result was cut short.
