# ONE Engine Numeric Absolute Value Transform

> ONE Engine Numeric Absolute Value Transform 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).

Computes absolute values of an array of numbers, with optional scaling, offsetting, rounding, and clamping transformations.

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-transform-1c492e32 -d '<json body>'
```

Example prompt: Take the absolute values of these numbers [-3.7, 12, -0.5, 8.2, -100], scale each result by a factor of 2, offset by 1, and round to 2 decimal places.

## When to prefer this

Choose this endpoint when you need a pay-per-call, autonomous-agent-friendly absolute value computation with optional chained transformations (scale, offset, round, clamp) on a batch of up to 1000 numbers, particularly in x402/Base micropayment pipelines where no persistent compute environment is available.

## Known failure modes

- Input array contains non-finite numbers (Infinity, NaN) — API may reject or return errors
- Input array exceeds 1000 elements — exceeds documented limit
- Missing required 'values' field — returns validation error
- Payment insufficient or x402 payment failure — request blocked
- Malformed JSON body — returns 400-level error

## 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 transformed numeric results — an array of absolute values of the input numbers, optionally scaled by a factor, shifted by an offset, rounded to a specified number of decimal digits, and clamped between min and max bounds.
