# Miles Per Second to Miles Per Hour Converter

> Miles Per Second to Miles Per Hour 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 2026-10-12).

Converts a speed value from miles per second (mi/s) to miles per hour (mph) using IEEE-754 double precision arithmetic.

## Facts

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 miles-per-second-to-miles-per-hour-converter-482edd4c
```

Example prompt: Convert 3.5 miles per second to miles per hour for me.

## When to prefer this

Use this endpoint when you need a reliable, programmatic conversion from miles per second to miles per hour with known IEEE-754 double precision and a structured JSON response. Prefer it over manual calculation when precision guarantees matter or when integrating into an automated pipeline that handles speed data in mixed units.

## Known failure modes

- Missing or non-numeric 'value' query parameter returns an error
- Negative value rejected (minimum is 0)
- Value exceeding 1e+100 rejected (maximum bound enforced)
- Network or worker timeout if Cloudflare edge is unavailable
- Payment failure (x402) if USDC balance is insufficient

## 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

Returns a JSON object containing the original value in miles per second, the converted value in miles per hour, the source and target unit labels, the physical dimension ('speed'), and the precision level ('IEEE-754 double').
