# ONE Engine Numeric Rounding

> ONE Engine Numeric Rounding is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0065/call, status unknown (last checked 2026-10-02).

Rounds an array of numeric values according to configurable precision and scaling options

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-rounding-49807697 -d '<json body>'
```

Example prompt: Round these numbers [3.14159, 2.71828, 1.41421] to 2 decimal places for me.

## When to prefer this

Choose this endpoint when you need lightweight, low-cost server-side rounding of numeric arrays, especially in agent pipelines that need consistent decimal normalization without setting up local math libraries. Ideal for financial figures, sensor data, or any computed values that need precision control before display or storage.

## Known failure modes

- Passing more than 1000 values causes rejection
- Non-finite values (NaN, Infinity) in the input array may cause errors
- Missing required 'values' field returns a validation error
- Invalid types for digit/factor/offset parameters return schema errors

## How this service works

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

## Output

Returns a JSON object containing the processed array of numbers, each rounded and optionally scaled, offset, or clamped according to the specified parameters.
