# ONE Engine Numeric Absolute Value Transformer

> ONE Engine Numeric Absolute Value Transformer is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).

Computes absolute values of an array of numbers, with optional normalization, scaling, and filtering parameters.

## 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-transformer-fa03340f -d '<json body>'
```

Example prompt: Take these numbers — [-3.7, 12, -0.5, 8.2, -100] — and give me their absolute values, rounded to 2 decimal digits.

## When to prefer this

Choose this endpoint when you need a cheap, pay-per-call absolute value computation over an array of up to 1000 numbers, especially with optional normalization, scaling, digit rounding, or clamping — all in one call. Prefer this over local computation when running inside a sandboxed agent environment without math libraries, or when you want a consistent, stateless numeric transform billed via x402 on Base.

## Known failure modes

- Empty or missing 'values' array returns a validation error
- More than 1000 values in the array exceeds the documented maximum and may be rejected
- Non-finite numbers (NaN, Infinity) in the input array may cause computation errors
- Invalid types (strings instead of numbers) in the values array will fail schema validation
- Payment failure via x402 protocol results in a 402 response before computation

## 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 array where each input value has been converted to its absolute value, with optional application of scaling (factor), offset, digit rounding, and min/max clamping. The response shape is flexible (additionalProperties: true).
