How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing the rescaled numeric values array, transformed according to the specified min/max bounds, optional factor, offset, and digit rounding. The output array maps the input values linearly into the target range.
Example use cases
Normalize ML features before training
“I have a list of raw feature values [0.5, 120, 3.7, 88, 14] that need to be normalized between 0 and 1 with 4 decimal places — can you rescale them for me?”
Rescale survey scores for display
“Take these survey response scores [1, 3, 2, 5, 4, 3, 1] and map them onto a 0 to 100 scale rounded to whole numbers so I can show them in a bar chart.”
Apply linear offset and factor to sensor data
“I've got sensor readings [10, 20, 30, 40, 50] and need to apply a scale factor of 1.5 and an offset of -5 to each, keeping 3 digits of precision — can you run that transformation?”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/linear-scale/t5?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a simple, fast, pay-per-call linear scaling of a numeric array without setting up your own math infrastructure. Ideal for agents doing on-the-fly normalization of ML features, sensor data, or display values where a local computation would add complexity. Best for arrays up to 1000 elements needing min/max normalization with optional rounding.
Side effects
- Input array exceeds 1000 elements — request rejected
- Non-finite numbers (NaN, Infinity) in the values array cause errors
- Invalid min/max range (min >= max) may produce undefined scaling behavior
- Missing required 'values' field returns a validation error
- Payment failure via x402 prevents execution
