ONE Engine Linear Scale (Numeric)
x402
ONE Engine Linear Scale (Numeric) 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).
Applies a linear scaling transformation to an array of numbers, mapping values to a target range or scale with optional offset, factor, rounding, and size control.

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 linearly scaled output array. Values are transformed according to the provided min/max bounds, factor, offset, and rounding (digits) parameters. The output reflects the rescaled numeric sequence, optionally resized to the requested number of elements.
Example use cases
Normalize ML feature values
“I have a list of raw feature values [0.5, 3.2, 7.8, 1.1, 9.4] that I need normalized between 0 and 1 with 4 digits of precision before feeding them into my model — can you do that?”
Rescale survey scores to percentage
“Take these survey response scores [1, 3, 5, 2, 4, 5, 1] and rescale them from their original 1–5 range to a 0–100 percentage scale, rounded to the nearest whole number.”
Apply gain and offset to sensor data
“Apply a linear scale to my sensor readings [200, 350, 410, 180, 295] using a factor of 0.5 and an offset of 10, and give me the results with 3 decimal places.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/linear-scale/t1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap, fast, pay-per-call linear normalization or rescaling of a numeric array — especially in autonomous agent workflows where you want deterministic math without spinning up your own compute. Ideal for preprocessing pipelines, score normalization, sensor data rescaling, or any scenario requiring min-max or factor+offset linear transforms at sub-cent cost via x402 on Base.
Side effects
- Array exceeds 1000 element limit — request rejected
- Non-finite numbers (NaN, Infinity) in input values array — validation error
- Invalid type for numeric parameters (e.g. string passed as min/max) — schema error
- Payment not included or insufficient — HTTP 402 response
- Empty values array — may return empty result or error
