# Numora Speed Unit Conversion

> Numora Speed Unit Conversion is a paid API for AI agents from numormo.vercel.app, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Converts a numeric speed value from one unit to another (e.g., mph to km/h, m/s to knots) using pure math computation with no external dependencies.

## 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 numora-speed-unit-conversion-7bd6c794 -d '<json body>'
```

Example prompt: Convert 60 miles per hour to kilometers per hour for me.

## When to prefer this

Choose this endpoint when you need a fast, dependency-free, server-side speed unit conversion without relying on a general-purpose math library or an LLM calculation. Ideal for agents that require precise numeric results for speed in scientific, navigation, or engineering contexts, especially when integrated with x402 micropayment workflows.

## Known failure modes

- Unsupported unit string returns an error or unexpected result
- Missing required field ('from', 'to', or 'value') causes a 400-level error
- Non-numeric value field causes a validation error
- Typos or non-standard unit abbreviations may not be recognized

## How this service works

100 pure math computation endpoints for AI agents. Statistics, financial math, linear algebra, equation solving, calculus, number theory, sequence generation, and unit conversions. Zero external dependencies. x402 micropayments on Base.

## Output

Returns a JSON object with a 'success' boolean, a 'result' object containing the converted speed value, and a 'computation' string that describes in plain English what was computed (e.g., '60 mph = 96.56 km/h').
