# SignalDesk AI Knot to Mile-per-Second Converter

> SignalDesk AI Knot to Mile-per-Second 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 speed value from knots to miles per second using IEEE-754 double precision arithmetic.

## Facts

- Endpoint: GET https://x402-agent.kariguetoazul.workers.dev/api/units/speed/knot-to-mile-per-second?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-knot-to-mile-per-second-converter-6e057a36

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-knot-to-mile-per-second-converter-6e057a36
```

Example prompt: What is 123.45 knots converted to miles per second?

## When to prefer this

Use this endpoint when you need a fast, cheap, precise programmatic conversion from knots to miles per second and do not want to implement the arithmetic yourself. Ideal for agents or workflows that process nautical or aviation speed data and need SI-compatible unit normalization at scale for $0.001 per call.

## Known failure modes

- Missing or non-numeric 'value' query parameter returns an error
- Negative input values are rejected (minimum is 0)
- Values exceeding 1e+100 are rejected (maximum enforced by schema)
- Non-GET/HEAD/DELETE HTTP methods return method-not-allowed errors

## 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 knots, the converted speed in miles per second as an IEEE-754 double, the source and target unit labels ('knot' and 'mile-per-second'), and the dimension ('speed').
