ONE Engine Numeric Normalize Range (T9)
x402
ONE Engine Numeric Normalize Range (T9) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.018/call, status unknown (last checked 2026-10-02).
Normalizes an array of numbers to a specified range or scale using configurable min, max, size, digits, factor, and offset 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 normalized numeric values rescaled according to the specified min, max, factor, offset, and digit precision parameters. The output maps input values proportionally into the target range.
Example use cases
ML Feature Scaling Before Model Inference
“I have a batch of raw feature values [250, 780, 430, 120, 900] and I need them all scaled between 0 and 1 with 3 decimal places before I feed them into my model — can you normalize that array?”
Sensor Data Rescaling for Dashboard
“These temperature sensor readings [15.2, 22.8, 30.1, 8.5, 41.7] need to be rescaled to fit between -10 and 10 with 2 decimal digits for my dashboard display — please normalize them.”
Score Normalization for Ranking System
“I have raw relevance scores [0.003, 0.041, 0.0012, 0.089, 0.055] and I want them mapped to a 0–100 range with an offset of 0 and 1 decimal digit precision so I can rank results meaningfully.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/normalize-range/t9?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-call numeric normalization without spinning up your own compute infrastructure — especially in agentic workflows on Base using x402 micropayments where you want stateless, low-cost numerical preprocessing on arrays up to 1000 elements.
Side effects
- Array exceeds 1000 elements — request rejected
- Non-finite values (NaN, Infinity) in the input array — validation error
- Missing required 'values' field — 400 bad request
- Payment not provided or insufficient — 402 payment required
- Min equals max causing division-by-zero normalization — undefined behavior or error
