ONE Engine Numeric Normalize Range
x402
ONE Engine Numeric Normalize Range is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).
Normalizes an array of numbers to a specified range, applying optional scaling, rounding, and offset transformations.

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 normalized array of numbers, rescaled according to the specified min/max bounds and optionally rounded to the given number of decimal digits, with any factor or offset applied.
Example use cases
ML feature normalization before training
“I have these raw feature values [12, 45, 3, 99, 67, 28] and I need them normalized between 0 and 1 with 4 decimal places of precision before feeding them into my model.”
Rescale user scores to percentile range
“Take these raw user engagement scores [150, 320, 88, 410, 275] and rescale them to a 0-to-100 range, rounded to 1 decimal place.”
Normalize sensor readings to calibrated band
“I'm getting raw sensor readings [0.3, 1.7, 0.9, 2.4, 1.1] and need them normalized between -1 and 1 with 2 decimal digits so I can compare them across devices.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/normalize-range/t8?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-call numeric range normalization without managing your own compute infrastructure. Ideal for agents that occasionally need to normalize small batches (up to 1000 values) on demand without setting up a data pipeline. At $0.01 USDC per call on Base via x402, it is cost-effective for sporadic normalization tasks in autonomous workflows.
Side effects
- Array contains non-finite values (Infinity, NaN) — likely validation error
- Array exceeds 1000 elements — rejected
- Missing required 'values' field — 400 error
- Min equals max causing division by zero in normalization
- Payment not provided or insufficient — 402 Payment Required
