# Mat Web & Data Toolkit – Unit Converter

> Mat Web & Data Toolkit – Unit Converter is a paid API for AI agents from automatom.matt-d59.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-18).

Converts a numeric value between units of measurement (e.g. miles to kilometers) and returns the result with category metadata as JSON.

## Facts

- Endpoint: GET https://automatom.matt-d59.workers.dev/convert?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown

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 mat-web-data-toolkit-unit-converter-4154f88f
```

Example prompt: Convert 10 miles to kilometers for me and give me the result as a number.

## When to prefer this

Use this endpoint when you need a quick, programmatic unit conversion with structured JSON output — especially useful when building agents or workflows that need to normalize measurements across different systems (imperial vs metric) without relying on a general-purpose LLM calculation that might hallucinate. Prefer this over a web-scraping call for simple numeric conversions.

## Known failure modes

- Unsupported unit pair returns an error or empty result
- Missing required query parameters (value, from, to) cause a 400-style error
- Incompatible unit categories (e.g. converting miles to kilograms) may return an error
- Non-numeric value input causes a parse error
- Payment failure or insufficient USDC balance blocks the request

## How this service works

Fetches a public web page and returns its title, meta description, outbound links and readable plain text as JSON.

## Output

A JSON object containing the original value, source unit, target unit, the converted numeric result, and the measurement category (e.g. 'length', 'weight'). Example: {"to":"km","from":"mi","value":10,"result":16.09344,"category":"length"}.
