# ONE Engine Numeric Absolute Value

> ONE Engine Numeric Absolute Value is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0015/call, status unknown (last checked 2026-10-02).

Computes the absolute value of an array of numbers, with optional scaling, rounding, and range-filtering controls.

## Facts

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-absolute-value-c14f2892 -d '<json body>'
```

Example prompt: Take this list of numbers — [-3.7, 12.4, -0.5, 8.0, -99.1] — and give me the absolute value of each, rounded to 1 decimal place.

## When to prefer this

Use this endpoint when an agent needs to programmatically compute absolute values on a batch of numbers (up to 1000) with optional rounding, scaling, offset, and range filtering — especially in autonomous pipelines where spinning up a code interpreter would be slower or unavailable. At $0.0015 USDC per call it is cost-effective for repeated lightweight math transformations in agentic workflows on Base.

## Known failure modes

- Array exceeds 1000 elements — request rejected
- Non-finite values (NaN, Infinity) in input array — may error or be skipped
- Payment not attached or insufficient — HTTP 402 returned
- Invalid type for 'digits' (non-integer) — schema validation failure
- Empty values array — may return empty result 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 computed absolute values of the input array, optionally rounded to a specified number of decimal digits, scaled by a factor, shifted by an offset, and filtered to a min/max range or truncated to a specified output size.
