# Rankine to Fahrenheit Temperature Converter

> Rankine to Fahrenheit Temperature 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 temperature value from degrees Rankine to degrees Fahrenheit using IEEE-754 double precision arithmetic.

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 rankine-to-fahrenheit-temperature-converter-f9a47d64
```

Example prompt: Convert 671.67 degrees Rankine to Fahrenheit for me.

## When to prefer this

Choose this endpoint when you need a precise, programmatic Rankine-to-Fahrenheit conversion with a structured JSON response, especially in agentic workflows that require machine-readable output including unit metadata. It is the right choice when working with thermodynamic or engineering data in the Rankine absolute temperature scale and needing Fahrenheit equivalents without implementing the formula manually.

## Known failure modes

- Missing required 'value' query parameter returns an error
- Value below minimum (0) may be rejected or produce an out-of-range error
- Non-numeric input for 'value' causes a validation error
- Payment failure (x402 protocol) blocks access if USDC payment is not completed
- Value exceeding 1e+100 maximum is rejected by schema validation

## 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

Returns a JSON object with the original value in Rankine, the converted value in Fahrenheit (IEEE-754 double precision), the source and target unit labels, and the physical dimension ('temperature').
