# Numora Energy Unit Conversion

> Numora Energy Unit Conversion 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 energy values between different units (e.g. joules, calories, kilowatt-hours, BTU) using pure mathematical computation

## Facts

- Endpoint: POST https://numomo.vercel.app/api/convert/energy
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/numora-energy-unit-conversion-953cc527
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_z-j2h7Tm51zD032y2kn9l

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-energy-unit-conversion-953cc527 -d '<json body>'
```

Example prompt: Convert 3500 joules to kilocalories for me.

## When to prefer this

Choose this endpoint when you need a fast, dependency-free, purely mathematical energy unit conversion without calling a general-purpose LLM or a heavyweight unit-conversion library. Ideal for agents doing physics, engineering, nutrition, or energy cost calculations that require precise numeric outputs and a structured JSON response. Costs $0.02 USDC per call via x402 micropayments on Base.

## Known failure modes

- Unsupported or misspelled unit name in 'from' or 'to' fields returns an error
- Missing required fields (value, from, to) returns validation error
- Non-numeric value provided returns schema error
- Extreme values (e.g. Infinity, NaN) may cause computation errors

## 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' containing the converted numeric value in the target energy unit, a 'success' boolean, and a 'computation' string describing the conversion performed (e.g. '3500 joules converted to kilocalories = 0.8359 kcal').
