## 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 mmhg-to-atmospheres-pressure-converter-839d7a64
```

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

## When to prefer this

Use this endpoint when you need a quick, single-value pressure conversion from mmHg to atmospheres without setting up local conversion logic. Ideal for scientific, medical, or meteorological contexts where pressure readings in mmHg need to be expressed in atm units.

## Known failure modes

- Missing 'value' query parameter returns an error
- Non-numeric value string causes a parse or validation error
- Negative values may return an error or unexpected result depending on server validation
- Network timeout or service unavailability returns a 5xx error

## How this service works

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

## Output

Returns the converted pressure value in standard atmospheres (atm) corresponding to the input value provided in millimeters of mercury (mmHg).
