# SignalDesk AI Centimeter to Kilometer Converter

> SignalDesk AI Centimeter to Kilometer Converter is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-13).

Converts a numeric length value from centimeters to kilometers using IEEE-754 double precision arithmetic.

## Facts

- Endpoint: GET https://x402-agent.kariguetoazul.workers.dev/api/units/length/centimeter-to-kilometer?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/signaldesk-ai-centimeter-to-kilometer-converter-7a1bf31a

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 signaldesk-ai-centimeter-to-kilometer-converter-7a1bf31a
```

Example prompt: Convert 50000 centimeters to kilometers for me.

## When to prefer this

Use this endpoint when you need a reliable, paid, auditable centimeter-to-kilometer conversion with IEEE-754 precision guarantees via the x402 micropayment protocol. Prefer it in automated pipelines where explicit precision documentation is required, or when integrating with other SignalDesk AI unit-conversion endpoints on the same host.

## Known failure modes

- Missing required 'value' query parameter returns an error
- Negative values are rejected (minimum is 0)
- Values exceeding 1e+100 are rejected (maximum bound enforced)
- Non-numeric input types cause validation failure
- Payment failure (HTTP 402) if USDC micropayment is not provided

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

A JSON object containing the original value in centimeters, the converted value in kilometers, the source unit ('centimeter'), the target unit ('kilometer'), the dimension ('length'), and the precision standard used ('IEEE-754 double').
