# SignalDesk AI – Milligram to Gram Converter

> SignalDesk AI – Milligram to Gram 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 grams using IEEE-754 double precision arithmetic.

## Facts

- Endpoint: GET https://x402-agent.kariguetoazul.workers.dev/api/units/mass/milligram-to-gram?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-milligram-to-gram-converter-6d4ec68f
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_uSA7aUsRiToC_iwXOH5MV

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-gram-converter-6d4ec68f
```

Example prompt: Convert 500 milligrams to grams for me.

## When to prefer this

Use this endpoint when you need a fast, programmatic, pay-per-call milligram-to-gram conversion with a structured JSON response including precision metadata. Prefer it in agent workflows where unit normalization needs to be auditable and deterministic rather than computed inline. It is appropriate when the calling agent does not want to implement conversion logic itself or needs a canonical, bounded-execution computation with a clear cost ($0.001 USDC per call).

## Known failure modes

- Missing required 'value' query parameter returns an error
- Negative value rejected (minimum is 0)
- Value exceeding 1e+100 rejected (maximum constraint)
- Non-numeric value for 'value' parameter causes validation failure
- Network timeout or Cloudflare Worker cold-start delay on first call

## 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, the source unit ('milligram'), the target unit ('gram'), the converted numeric result (IEEE-754 double precision), and the dimension label ('mass').
