# ONE Engine Numeric Absolute Value (T1)

> ONE Engine Numeric Absolute Value (T1) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0005/call, status unknown (last checked 2026-10-02).

Computes absolute values of an array of up to 1000 numbers, with optional scaling, clamping, offsetting, and digit-rounding transformations.

## Facts

- Endpoint: POST https://one-search.one-engine.workers.dev/v3/numeric/absolute/t1?utm_source=zero.xyz
- Price: $0.0005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-02
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/one-engine-numeric-absolute-value-t1-bdeffc17

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-t1-bdeffc17 -d '<json body>'
```

Example prompt: Take the absolute values of this list of numbers [-3.7, 12.1, -0.5, 99, -47.2], scale them by a factor of 2, and round to 1 decimal digit.

## When to prefer this

Choose this endpoint when you need a fast, cheap, pay-per-call absolute value transformation on a batch of numbers, especially when combined with scaling, clamping, or rounding in a single call. It is ideal for agentic pipelines that need lightweight numeric normalization without spinning up local compute, and when operating on Base with x402 micropayments at $0.0005 per call.

## Known failure modes

- Array exceeds 1000 elements — request rejected
- Non-finite values (NaN, Infinity) in the input array — may cause computation errors
- Missing required 'values' field — validation error returned
- Payment not included or insufficient — 402 Payment Required response
- Type mismatch (e.g. strings in numeric array) — schema validation failure

## How this service works

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

## Output

Returns a JSON object containing an array of transformed numeric values where each input has been converted to its absolute value and optionally scaled by a factor, offset by a constant, clamped to a min/max range, and rounded to a specified number of decimal digits. The response structure follows the generic additionalProperties schema, so the exact output key names may vary.
