# ApexAPI Pressure Unit Converter

> ApexAPI Pressure Unit Converter is a paid API for AI agents from apex-api-gamma.vercel.app, paid per call via x402, $0.189918/call, status unknown (last checked 2026-10-11).

Converts pressure values between different units (e.g. Pascal, bar, PSI, atm, mmHg)

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 apexapi-pressure-unit-converter-dce97208 -d '<json body>'
```

Example prompt: Convert 14.7 PSI to bar for me — I need the equivalent pressure value in bar units.

## When to prefer this

Use this endpoint when you need a quick, pay-per-call pressure unit conversion without setting up API keys. Ideal for agents needing on-demand unit conversion across common pressure units (PSI, bar, Pascal, atm, mmHg, torr, kPa) in engineering, science, or weather contexts.

## Known failure modes

- Invalid or unrecognized pressure unit string returns an error
- Missing input value or unit causes a 400 bad request
- Ambiguous query string may return unexpected conversion
- Payment failure in USDC results in 402 response and no conversion result

## How this service works

Crypto, AI, Social Media, Finance, Weather, Tools &amp; more. Pay per call in USDC on Base. No API keys.

## Output

Returns the converted pressure value expressed in the target unit, given an input pressure and source/target unit specification.
