# Numora Volume Unit Conversion API

> Numora Volume Unit 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 2026-09-15).

Converts a numeric value from one volume unit to another (e.g. liters to gallons, cubic meters to fluid ounces)

## Facts

- Endpoint: POST https://numomo.vercel.app/api/convert/volume
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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-api-8e9e4e2f -d '<json body>'
```

Example prompt: Convert 3.5 liters to US fluid ounces for me — use Numora's pure math volume converter with no external lookups.

## When to prefer this

Choose this endpoint when you need a fast, deterministic, offline volume unit conversion with no external API dependencies or data freshness concerns. Ideal for agents handling recipe scaling, scientific calculations, shipping logistics, or any workflow requiring reliable metric-to-imperial or inter-volume-unit conversion. Prefer this over general-purpose LLM math when you need guaranteed numeric accuracy and a structured response.

## Known failure modes

- Unsupported or misspelled unit strings in 'from' or 'to' fields result in an error response
- Missing required fields (value, from, to) cause a 400-level validation error
- Incompatible unit types (e.g. converting liters to kilograms) will fail since only volume units are supported
- Non-numeric 'value' input causes a schema 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 'success' boolean, a 'result' object containing the converted numeric value in the target unit, and a 'computation' string describing the conversion performed (e.g. '3.5 liters = 118.35 fluid ounces').
