# Numora Length Unit Conversion

> Numora Length 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 2026-09-15).

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

## Facts

- Endpoint: POST https://numorapoi.orbonomy.xyz/api/convert/length
- 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-length-unit-conversion-b84085be
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_6jEwR8S1uSlsio7ldmIWu

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-b84085be -d '<json body>'
```

Example prompt: Convert 26.2 miles to kilometers using pure math computation — no rounding, exact result.

## When to prefer this

Use this endpoint when you need precise, dependency-free length unit conversions via a simple API call with micropayment access on Base. Prefer over browser-based converters or heavier math libraries when operating in an agentic pipeline that already supports x402 payments and needs a clean JSON result with a computation description.

## Known failure modes

- Unrecognized unit string for 'from' or 'to' field — returns error or success:false
- Missing required fields (value, from, to) — likely 400 Bad Request
- Payment not included or insufficient — 402 Payment Required
- Value is not a valid number — schema validation error
- Incompatible unit types (e.g. miles to liters) — returns error

## 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 flag, a result object containing the converted numeric value, and a human-readable computation string describing what was computed (e.g. '26.2 miles converted to kilometers').
