# SignalDesk AI – Megapascal to Atmosphere Pressure Converter

> SignalDesk AI – Megapascal to Atmosphere Pressure Converter is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-13).

Converts a pressure value from megapascals (MPa) to atmospheres (atm) using IEEE-754 double precision arithmetic.

## Facts

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 signaldesk-ai-megapascal-to-atmosphere-pressure-converter-a7e51a87
```

Example prompt: Convert 123.45 megapascals to atmospheres for me — I need the exact numeric result.

## When to prefer this

Use this endpoint when an agent needs a fast, low-cost, machine-precise conversion from megapascals to atmospheres without relying on a general-purpose LLM calculation. Ideal for scientific, engineering, or industrial contexts where IEEE-754 double precision matters and a deterministic numeric result is required. Prefer it over LLM arithmetic for guaranteed accuracy.

## Known failure modes

- Missing or non-numeric 'value' query parameter returns a validation error
- Negative value rejected (minimum: 0 enforced by schema)
- Value exceeding 1e+100 rejected by schema maximum constraint
- Payment not provided or insufficient USDC results in HTTP 402 response
- Network or Cloudflare Worker timeout on overloaded edge node

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

A JSON object containing the original value in megapascals, the converted value in standard atmospheres (atm), the source and target unit labels ('megapascal' and 'atmosphere'), the dimension ('pressure'), and the precision used ('IEEE-754 double').
