## 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

```

Example prompt: Convert 250 pounds to kilograms for me.

## When to prefer this

Choose this endpoint when an agent needs a fast, reliable, programmatic unit conversion without relying on LLM arithmetic. Ideal for pipelines that process user-supplied measurements in mixed unit systems, e.g. international e-commerce, scientific data normalization, recipe apps, or IoT sensor data harmonization. Covers a broad range of everyday categories (length, mass, volume, data size, time, speed, temperature) in a single endpoint.

## Known failure modes

- Unsupported unit type or unit name returns a 400 error with details about valid units
- Incompatible unit categories (e.g. converting length to mass) return an error indicating mismatched types
- Non-numeric or missing input value returns a validation error
- Extremely large or small values may cause precision issues in floating-point output

## How this service works

Convert length, mass, volume, data-size, time, speed, or temperature between units.

## Output

Returns the converted numeric value in the requested target unit, along with the source and target unit labels and optionally the conversion factor used.
