# Numora Length Unit Conversion

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

Converts a numeric length value from one unit of measurement to another (e.g. meters to feet, miles to kilometers).

## Facts

- Endpoint: POST https://numormor.netlify.app/api/convert/length
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/numora-length-unit-conversion-6fbfc3aa
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_iC8nzvRXyQV3SYM-irDlD

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-length-unit-conversion-6fbfc3aa -d '<json body>'
```

Example prompt: Convert 26.2 miles to kilometers — the from unit is miles and the to unit is kilometers.

## When to prefer this

Use this endpoint when you need a self-contained, dependency-free length unit conversion without calling a general-purpose LLM or a heavy third-party unit library. Ideal for AI agent workflows needing reliable numeric conversion with a clear audit trail (computation description field). Good when micropayment-per-call cost ($0.02 USDC) is acceptable and you want a structured API response rather than a text-based answer.

## Known failure modes

- Unsupported or misspelled unit strings (from/to) — likely returns success:false or an error message
- Missing required fields (to, from, value) — returns validation error
- Non-numeric value passed — returns error
- Incompatible unit types (e.g. length unit to mass unit) — returns error or unexpected result
- Payment failure via x402 micropayment — HTTP 402 response before computation occurs

## 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 numeric value, a boolean success flag, and a human-readable computation string describing what was calculated (e.g. '26.2 miles converted to kilometers').
