## 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-mmhg-to-kilopascals-pressure-converter-54bdaea8
```

Example prompt: Can you convert 760 mmHg to kilopascals for me?

## When to prefer this

Use this endpoint when you need a quick, programmatic conversion of a single pressure value from millimeters of mercury (mmHg) to kilopascals (kPa), especially in agentic workflows where a dedicated unit-conversion microservice is preferable to implementing the formula inline.

## Known failure modes

- Missing required 'value' query parameter returns an error
- Non-numeric value passed causes a parsing or validation error
- Negative or out-of-range value may return an unexpected result or error
- Payment failure (x402) returns a 402 Payment Required response

## How this service works

Convert mmhg to kilopascals (pressure). Pass ?value=N.

## Output

Returns the converted pressure value in kilopascals (kPa) corresponding to the input mmHg value provided via the query parameter.
