## 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 electronvolts-to-kilojoules-converter-d6e1155c
```

Example prompt: Convert 6.24 electronvolts to kilojoules for me.

## When to prefer this

Use this endpoint when you need a quick, accurate programmatic conversion from electronvolts to kilojoules, particularly in physics, chemistry, or materials science contexts where energy values are expressed at the atomic or subatomic scale and need to be expressed in SI-adjacent units.

## Known failure modes

- Missing or non-numeric value parameter returns an error
- Very large or very small numbers may exceed floating-point precision
- Non-numeric string input (e.g. 'five') may return 400 or NaN result
- Service unavailable or payment failure returns 402 or 5xx

## How this service works

Convert electronvolts to kilojoules (energy). Pass ?value=N.

## Output

A numeric value representing the input energy expressed in kilojoules, derived by multiplying the electronvolt value by the standard conversion factor (approximately 1.602176634 × 10⁻²² kJ per eV).
