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, $0.004/call, status unknown (last checked 2026-10-02).
Computes absolute values of an array of numeric inputs, with optional scaling, offsetting, and digit-rounding controls.

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 array of absolute values, with optional min/max clamping, factor scaling, offset application, and digit rounding applied as specified. The response schema is open (additionalProperties: true), so may include metadata or auxiliary fields.
Example use cases
Clean signed sensor readings
“I have these raw sensor readings that can go negative due to calibration drift: [-0.5, 1.2, -3.1, 0.8, -2.2]. Can you take the absolute values and round each to 2 decimal places so I can use them downstream?”
Normalize financial deltas
“Here are my portfolio daily change values: [-150.5, 200.0, -75.25, 0, 320.1]. I want the absolute value of each scaled by a factor of 0.01 so I get fractional form, offset by 0.001.”
Prepare magnitude array for plotting
“I need the absolute values of this dataset [-5, -3, -1, 0, 1, 3, 5] clamped between 0 and 4, rounded to whole integers, so I can use them as bar chart heights.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/absolute/t6?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap, pay-per-call absolute value transformation for up to 1000 numbers, especially with combined scaling, offsetting, clamping, or digit-precision options in a single call. It is ideal for autonomous agents running on Base that want deterministic numerical processing without spinning up compute infrastructure. Prefer it over general-purpose math libraries when operating in an agentic pipeline that already uses x402 micropayments.
Side effects
- Array exceeds 1000 element limit — request rejected
- Non-finite values (NaN, Infinity) in the values array — validation error
- Payment failure via x402 on Base — 402 response, no computation performed
- Malformed JSON body — 400 bad request
- Invalid type for numeric parameters (e.g. string instead of number) — schema validation error
