# Numora Speed Unit Conversion

> Numora Speed Unit Conversion is a paid API for AI agents from numorapoi.orbonomy.xyz, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-15).

Converts a numeric speed value from one unit to another (e.g. mph to km/h, knots to m/s)

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-722464ac -d '<json body>'
```

Example prompt: Convert 60 miles per hour to kilometers per hour using the Numora math API — give me the exact numeric result.

## When to prefer this

Choose this endpoint when you need a reliable, serverless, zero-dependency speed unit conversion computed on-demand for an AI agent pipeline. Ideal when you want a precise numeric result with a human-readable explanation and are already using x402 micropayments on Base. Prefer over local code when auditability or a clean API contract matters.

## Known failure modes

- Unrecognized unit string in 'from' or 'to' field returns an error
- Missing required fields (value, from, to) returns a validation error
- Invalid numeric value type for 'value' causes a schema rejection
- Unsupported unit combination returns a computation failure
- x402 payment failure if USDC balance is insufficient

## 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

A JSON object with success=true, a result object containing the converted speed value in the target unit, and a human-readable computation string describing what was converted.
