# SignalDesk AI Millimeter to Mile Converter

> SignalDesk AI Millimeter to Mile 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 length value from millimeters to miles using IEEE-754 double precision arithmetic

## Facts

- Endpoint: GET https://x402-agent.kariguetoazul.workers.dev/api/units/length/millimeter-to-mile?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-13

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-millimeter-to-mile-converter-0d01ff9b
```

Example prompt: Can you convert 123.45 millimeters to miles for me?

## When to prefer this

Use this endpoint when you need a precise, programmatic millimeter-to-mile conversion as part of an automated workflow, especially when calling via the x402 micropayment protocol. It is ideal for agents performing unit normalization on sensor or engineering data. Prefer it over general-purpose LLM math when you need guaranteed IEEE-754 double precision and a structured JSON response.

## Known failure modes

- Missing required 'value' query parameter returns an error
- Negative value rejected (minimum is 0)
- Value exceeding 1e+100 rejected (maximum enforced)
- Non-numeric value for 'value' parameter returns validation error
- Payment failure (x402 protocol) if USDC not provided or insufficient balance

## 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 and unit (millimeter), the converted value in miles as an IEEE-754 double-precision float, the dimension (length), and precision metadata. Example: {from: 'millimeter', to: 'mile', value: 123.45, converted: 0.00007670827368169888, dimension: 'length', precision: 'IEEE-754 double'}.
