# Numora Weight Conversion API

> Numora Weight Conversion API is a paid API for AI agents from numomo.vercel.app, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-16).

Converts a numeric weight value from one unit to another (e.g. kilograms to pounds) 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-weight-conversion-api-749056d0 -d '<json body>'
```

Example prompt: Convert 75 kilograms to pounds for me.

## When to prefer this

Use this endpoint when you need a fast, serverless, dependency-free weight unit conversion in an agent pipeline — especially when paying per-call via x402 micropayments on Base is acceptable and you want a dedicated math computation service rather than a general-purpose LLM or a heavy unit-conversion library.

## Known failure modes

- Unknown or unsupported unit strings in 'from' or 'to' fields return an error
- Missing required fields ('from', 'to', 'value') cause a 400-level error
- Non-numeric 'value' input causes a validation failure
- Incompatible unit categories (e.g. passing a length unit to a weight endpoint) may return an error or unexpected result

## 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 'result' object containing the converted value, a 'success' boolean (always true on success), and a 'computation' string describing in plain language what was computed (e.g. '75 kilograms = 165.35 pounds').
