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 nexusapi-energy-unit-converter-0f9c88d0 -d '<json body>'
```

Example prompt: Convert 2500 kilocalories to kilojoules for me.

## When to prefer this

Use this endpoint when you need a quick, pay-per-call energy unit conversion without setting up API keys. It is well-suited for AI agent pipelines that occasionally need to normalize energy values across domains like nutrition, physics, or electrical engineering, and where integrating a full math/unit-conversion SDK is overkill.

## Known failure modes

- Unrecognized unit names in the query string may return an error or null result
- Ambiguous query format (missing source or target unit) may yield incorrect conversion
- Very large or very small numbers may cause precision issues in the response
- Service unavailability on the Vercel deployment may return a 503 or timeout

## How this service works

Crypto, AI, Social Media, Finance, Weather, Tools &amp; more. Pay per call in USDC on Base. No API keys.

## Output

Returns the converted energy value in the requested target unit, along with the conversion factor and the original input value, allowing the agent to display or use the numeric result directly.
