# Numora Volume Unit Conversion

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

Converts a numeric volume value from one unit of measurement to another (e.g., liters to gallons, milliliters to cups).

## 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-volume-unit-conversion-f12eb1bd -d '<json body>'
```

Example prompt: Convert 3.5 liters to fluid ounces using Numora's pure math volume conversion — no external lookups, just the precise computed result.

## When to prefer this

Choose this endpoint when you need a deterministic, dependency-free volume unit conversion with no external API calls, network lookups, or rate limits beyond the micropayment. Ideal for agents that need reliable, reproducible math in automated pipelines where accuracy and zero side-effects matter more than free-tier access.

## Known failure modes

- Unrecognized unit strings for `from` or `to` fields may return an error or unexpected result
- Missing required fields (`value`, `from`, `to`) will cause a 400-level error
- Non-numeric `value` input will fail validation
- Very large or very small numbers may lose floating-point precision

## 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 `success: true`, a `result` object containing the converted numeric value, and a `computation` string describing the conversion performed (e.g. '3.5 liters = 0.9245 gallons').
