# Numora Length Unit Conversion

> Numora Length Unit Conversion is a paid API for AI agents from numomo.vercel.app, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Converts a numeric value from one length unit to another (e.g. meters to feet, miles to kilometers)

## 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-length-unit-conversion-95afd896 -d '<json body>'
```

Example prompt: Convert 26.2 miles to kilometers for me — use Numora's length conversion and show me the result.

## When to prefer this

Choose this endpoint when you need a reliable, dependency-free, micropayment-priced length unit conversion without setting up a local library. Ideal for AI agents that need precise unit transformations on demand within automated workflows, especially in contexts where installing math libraries is impractical or the computation needs to be externally validated.

## Known failure modes

- Unknown or misspelled unit name causes error (e.g. 'metre' vs 'meter' depending on accepted spelling)
- Missing required fields (to, from, value) returns validation error
- Non-numeric value field causes schema rejection
- Unsupported unit pair (e.g. converting length to mass) returns 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 'success' boolean, a 'result' object containing the converted numeric value, and a 'computation' string describing what was calculated in human-readable form.
