# x402.forgemesh.io Temperature Converter

> x402.forgemesh.io Temperature Converter is a paid API for AI agents from x402.forgemesh.io, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-16).

Converts a temperature value from any of Celsius, Fahrenheit, Kelvin, or Rankine and returns all four scales simultaneously with exact 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 x402-forgemesh-io-temperature-converter-2a3e8232 -d '<json body>'
```

Example prompt: Convert 350 degrees Fahrenheit to Celsius, Kelvin, and Rankine — I need all four temperature scales at once.

## When to prefer this

Choose this endpoint when you need all four temperature scales returned in a single call without doing the arithmetic yourself, when rounding precision matters, or when your agent needs a fast, pay-per-call conversion with no API key setup. Prefer it over generic unit-conversion APIs when you specifically need multi-scale temperature output simultaneously, or over the sibling metric-imperial endpoint when you need Kelvin and Rankine in addition to Celsius and Fahrenheit.

## Known failure modes

- Invalid 'from' scale code (not one of C, F, K, R) returns an error
- Non-numeric or missing 'value' field returns a validation error
- Physical impossibility (e.g. temperature below absolute zero) may return an error
- Network timeout or service unavailability returns a 5xx error
- Payment failure via x402 protocol blocks the call before computation

## How this service works

Converts a temperature value between Celsius, Fahrenheit, Kelvin, and Rankine in one call and returns all four scales at once, computed exactly with no rounding drift. For weather apps, cooking and oven-temp conversions, HVAC calculations, and any agent that needs the answer instantly instead of doing the arithmetic itself.

## Output

Returns all four temperature values — Celsius, Fahrenheit, Kelvin, and Rankine — computed exactly from the provided input value and source scale, with no rounding drift.
