# SignalDesk AI – Hour to Minute Converter

> SignalDesk AI – Hour to Minute 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 value in hours to minutes 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 signaldesk-ai-hour-to-minute-converter-c2df4ff2
```

Example prompt: Convert 2.5 hours to minutes for me.

## When to prefer this

Use this endpoint when you need a reliable, precise, machine-readable hour-to-minute conversion with structured JSON output including unit metadata, especially inside automated pipelines or agents where parsing a plain text answer would be fragile. It is overkill for simple mental math but ideal when you need IEEE-754 precision guarantees and a canonical response schema.

## Known failure modes

- Missing required 'value' query parameter returns an error
- Non-numeric or negative value may be rejected (minimum is 0)
- Extremely large values (above 1e+100) are outside the allowed range
- Payment not included or insufficient USDC results in 402 Payment Required
- Network or Cloudflare Worker downtime causes 503 or timeout

## 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 with the original value in hours, the converted value in minutes as an integer, the source unit ('hour'), the destination unit ('minute'), the dimension label ('time'), and the precision method ('IEEE-754 double').
