ONE Engine Numeric Absolute Value
x402
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.

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.
Example use cases
Magnitude from signed financial deltas
“I have daily P&L changes like [-150.25, 320.00, -87.50, 0.00, -412.75] — can you compute the absolute value of each so I can see the raw magnitude of movement regardless of direction, rounded to 2 decimal places?”
Normalize sensor error readings
“These sensor error readings include negative values: [-0.023, 0.041, -0.117, 0.005, -0.089]. Get me the absolute value of each so I can work with error magnitudes only.”
Scale and clamp absolute values
“Take these numbers [-500, 200, -800, 150, -50, 900], compute their absolute values, scale everything by a factor of 0.01, and only return results between 0 and 5.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/absolute/t4?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
