# ONE Engine Numeric Normalize Range (T9)

> ONE Engine Numeric Normalize Range (T9) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.018/call, status unknown (last checked 2026-10-02).

Normalizes an array of numbers to a specified range or scale using configurable min, max, size, digits, factor, and offset parameters.

## Facts

- Endpoint: POST https://one-search.one-engine.workers.dev/v3/numeric/normalize-range/t9?utm_source=zero.xyz
- Price: $0.018/call
- Payment: x402

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 one-engine-numeric-normalize-range-t9-ded2789b -d '<json body>'
```

Example prompt: Normalize these sensor readings [12.4, 87.3, 45.1, 3.9, 100.0] to a 0-to-1 range, rounded to 4 decimal digits.

## When to prefer this

Choose this endpoint when you need a fast, pay-per-call numeric normalization without spinning up your own compute infrastructure — especially in agentic workflows on Base using x402 micropayments where you want stateless, low-cost numerical preprocessing on arrays up to 1000 elements.

## Known failure modes

- Array exceeds 1000 elements — request rejected
- Non-finite values (NaN, Infinity) in the input array — validation error
- Missing required 'values' field — 400 bad request
- Payment not provided or insufficient — 402 payment required
- Min equals max causing division-by-zero normalization — undefined behavior or error

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

A JSON object containing the normalized numeric values rescaled according to the specified min, max, factor, offset, and digit precision parameters. The output maps input values proportionally into the target range.
