# Numora Weight Unit Conversion

> Numora Weight 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 2026-09-15).

Converts a numeric weight value from one unit of mass to another (e.g. kilograms to pounds)

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-unit-conversion-590036bd -d '<json body>'
```

Example prompt: Convert 75 kilograms to pounds for me — I need the exact numeric result.

## When to prefer this

Use this endpoint when an AI agent needs precise, programmatic weight unit conversion without relying on a general-purpose LLM calculation, and when a micropayment-based serverless math API is acceptable. Prefer this over LLM arithmetic when auditability or exactness of the conversion factor matters.

## Known failure modes

- Unrecognized unit string in 'from' or 'to' field returns an error
- Missing required fields (value, from, to) returns a 400-level error
- Payment not provided or insufficient triggers a 402 Payment Required response
- Value is non-numeric or null causes validation failure

## 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 weight value, a boolean success flag, and a human-readable computation string describing what was computed (e.g. '75 kg = 165.347 lbs').
