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 agent402-tools-electronvolts-to-kilowatt-hours-converter-1e3ccce8
```

Example prompt: Convert 5000000 electronvolts to kilowatt-hours for me.

## When to prefer this

Use this endpoint when you need a simple, reliable eV-to-kWh energy unit conversion without setting up a local formula. Ideal for agents handling scientific data pipelines, physics calculations, or energy analysis where electronvolt inputs need to be expressed in electrical power units. Prefer this over manual calculation when accuracy and convenience are priorities.

## Known failure modes

- Missing required 'value' query parameter returns an error
- Non-numeric value string causes conversion failure
- Extremely large or small values may exceed floating point precision
- Payment of 0.001 USDC not provided results in 402 Payment Required response

## How this service works

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

## Output

Returns the numeric equivalent of the input electronvolt value expressed in kilowatt-hours (kWh), enabling cross-unit energy comparisons between particle physics and electrical energy contexts.
