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 array of numbers, rescaled according to the specified min, max, factor, offset, and digit precision parameters.
Example use cases
ML feature scaling before training
“I have these raw feature values [0.5, 3.2, 1.8, 7.4, 2.1] that I need normalized between 0 and 1 with 4 decimal digits of precision before feeding them into my model — can you do that?”
Chart axis rescaling for dashboard
“Rescale these sensor readings [150, 320, 80, 500, 210] to fit between 0 and 255 so I can map them onto a color scale, rounded to whole numbers.”
Survey score standardization
“I've got survey results [4, 7, 2, 9, 5, 6, 1, 8] on a 1-10 scale and I want to normalize them to 0-100 with 1 decimal place — can you handle that?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/normalize-range/t3?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, cheap ($0.001 USDC), pay-per-call numeric normalization with flexible range, scaling factor, offset, and rounding — especially in agentic pipelines on Base that already use x402 payments and need lightweight math utilities without spinning up local compute.
Side effects
- Empty or missing 'values' array returns a validation error
- Array exceeds 1000 elements limit causing rejection
- Non-finite numbers (NaN, Infinity) in the array cause errors
- Invalid parameter types (e.g. string instead of number for min/max) return schema errors
- Payment failure via x402 prevents execution
