## 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 saylor-innovations-weight-converter-68a2689d
```

Example prompt: Convert 185 pounds to kilograms and show me the equivalents in all other weight units too.

## When to prefer this

Choose this endpoint when you need precise weight unit conversion with full cross-unit equivalents in a single call, especially when the user needs to see the value expressed simultaneously in multiple units. Prefer over manual calculation or general-purpose math tools when structured JSON output with formula and equivalents is desirable.

## Known failure modes

- Missing required query parameters (value, from, to) returns an error
- Unsupported unit string returns an error or empty result
- Non-numeric value parameter causes a conversion failure
- Payment not provided or insufficient USDC causes a 402 response
