# Numora Volume Unit Conversion

> Numora Volume 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 2026-09-14).

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

## Facts

- Endpoint: POST https://numorapoi.orbonomy.xyz/api/convert/volume
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

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-68e3b217 -d '<json body>'
```

Example prompt: Convert 3.785 liters to US gallons — give me the exact numeric result.

## When to prefer this

Choose this endpoint when you need a fast, serverless, dependency-free volume unit conversion with no rate limits beyond micropayment cost. Ideal for agents that need precise numeric conversions between volume units (liters, gallons, milliliters, cubic meters, fluid ounces, etc.) without calling a general-purpose LLM or maintaining local conversion logic.

## Known failure modes

- Unsupported or misspelled unit strings in 'from' or 'to' fields return an error
- Missing required fields (value, from, to) cause a 400-level error
- Non-numeric 'value' field causes a validation error
- Payment failure via x402 micropayment returns 402 Payment Required
- Incompatible unit types (e.g. volume vs mass) 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 'success' boolean, a 'result' object containing the converted numeric volume value, and a 'computation' string describing what was calculated in human-readable form.
