ONE Engine Linear Scale Normalizer
x402
ONE Engine Linear Scale Normalizer is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).
Linearly scales/normalizes an array of numeric values to a target range using configurable min, max, factor, offset, and precision parameters.

How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing the linearly scaled/normalized output values corresponding to the input array, transformed according to the specified min, max, factor, offset, and digits parameters.
Example use cases
Normalizing ML features before training
“I have these raw feature values [120, 450, 33, 780, 210] and I need them normalized to a 0-to-1 range with 4 decimal digits so I can feed them into my model — can you run them through the linear scale normalizer?”
Rescaling survey scores to percentages
“Take these survey response scores [2, 4, 1, 5, 3, 4] where the scale goes from 1 to 5, and rescale them to a 0-to-100 percentage range with no decimal places.”
Applying gain and offset to sensor data
“I've got sensor readings [0.02, 0.15, 0.08, 0.31, 0.27] and I need to apply a factor of 3.5 and an offset of -0.5 to each value — use the linear scale API and give me results to 3 decimal digits.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/linear-scale/t3?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, cheap ($0.001 USDC) serverless linear normalization of a numeric array without standing up your own compute. It is ideal for preprocessing steps in agent pipelines where data needs to be rescaled to a known range before downstream ML inference, visualization, or comparison operations. Prefer it over manual computation when operating in an autonomous agent context with x402 micropayment capability on Base.
Side effects
- More than 1000 values in the input array — request rejected
- Non-finite numbers (NaN, Infinity) in the values array — validation error
- Missing required 'values' field — 400 bad request
- Payment failure via x402 protocol — 402 payment required
- Malformed JSON body — parse error
