## 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 atmospheres-to-mmhg-pressure-converter-2c0c6ae5
```

Example prompt: Convert 2.5 atmospheres to mmHg for me.

## When to prefer this

Use this endpoint when you need a quick, programmatic conversion from atmospheres to mmHg and don't want to implement the formula manually. Ideal for scientific, medical, or meteorological contexts where pressure unit normalization is required within an automated workflow.

## Known failure modes

- Missing 'value' query parameter returns an error
- Non-numeric 'value' input causes a bad request or conversion error
- Payment failure (x402) if USDC micropayment is not completed
- Service unavailable if the agent402.tools host is down

## How this service works

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

## Output

Returns the equivalent pressure value in millimeters of mercury (mmHg) corresponding to the input value given in atmospheres.
