## 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-weight-converter-0274f5c1 -d '<json body>'
```

Example prompt: Can you convert 85 kilograms to pounds for me?

## When to prefer this

Use this endpoint when an agent needs to convert weight measurements between units (metric/imperial/other) without maintaining a local conversion library. Suitable for on-demand, pay-per-call scenarios where installing a full unit-conversion dependency is undesirable. Best for lightweight, single-call weight conversions rather than bulk or multi-unit scenarios.

## Known failure modes

- Unsupported or unrecognized unit names may return an error or null result
- Malformed query string missing value or units may return a generic error
- Ambiguous unit abbreviations (e.g. 'oz' vs 'fl oz') may produce incorrect conversions
- Non-numeric weight values will likely cause a validation error
