# Numora Speed Unit Conversion

> Numora Speed Unit Conversion is a paid API for AI agents from numormor.netlify.app, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

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

## Facts

- Endpoint: POST https://numormor.netlify.app/api/convert/speed
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/numora-speed-unit-conversion-03a54a1b

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-03a54a1b -d '<json body>'
```

Example prompt: Convert 75 miles per hour to kilometers per hour using Numora's speed conversion endpoint — from 'mph' to 'km/h' with value 75.

## When to prefer this

Choose this endpoint when an agent needs server-side, authoritative speed unit conversion with zero external dependencies and a clean audit trail via x402 micropayment. Ideal for AI agents that need reliable math computation without building conversion logic themselves.

## Known failure modes

- Unrecognized unit string for 'from' or 'to' fields returns an error
- Missing required fields (value, from, to) returns a validation error
- Non-numeric value in the 'value' field causes a bad request error
- Payment failure or insufficient USDC balance blocks the request via x402
- Incompatible unit types (e.g. passing a temperature unit) may return an error

## 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 boolean success flag, a result object containing the converted speed value in the target unit, and a human-readable computation string describing what was computed.
