# SignalDesk AI – Milligram to Kilogram Converter

> SignalDesk AI – Milligram to Kilogram 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 mass value from milligrams to kilograms using IEEE-754 double precision arithmetic.

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-milligram-to-kilogram-converter-96783a84
```

Example prompt: Convert 250 milligrams to kilograms for me — I need the precise numeric result.

## When to prefer this

Choose this endpoint when you need a fast, deterministic, pay-per-call milligram-to-kilogram conversion with a structured JSON response and IEEE-754 precision guarantees — particularly useful in automated pipelines where you want an external computation service rather than inline arithmetic, or when operating within the x402 micropayment ecosystem.

## Known failure modes

- Missing required 'value' query parameter returns a validation error
- Negative input value rejected (minimum: 0)
- Extremely large values beyond Number.MAX_VALUE may lose precision due to IEEE-754 limits
- Non-numeric 'value' parameter returns a type validation error
- Payment not provided or insufficient USDC results in HTTP 402 Payment Required

## 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 and unit ('milligram'), the converted value in kilograms, the target unit ('kilogram'), the physical dimension ('mass'), and a precision note ('IEEE-754 double'). Example: {"from":"milligram","to":"kilogram","value":123.45,"converted":0.00012345,"dimension":"mass","precision":"IEEE-754 double"}.
