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 to the specified min/max range, with optional rounding, factor scaling, offset adjustment, and size truncation applied as requested.
Example use cases
ML feature normalization pipeline
“I have these raw feature values [0.5, 120, 33, 7, 88, 201] and need them normalized to a 0-to-1 range with 6 decimal digits of precision before I feed them into my model.”
Score rescaling to percentage
“Rescale these exam scores [45, 78, 92, 61, 55, 88, 70] so that the lowest possible is 0 and the highest is 100, rounded to 2 decimal places.”
Bounded data capping for visualization
“Take these temperature readings [-5, 12, 34, 67, 102, 88, 45] and normalize them to fit between 10 and 90, applying a factor of 1.2 and an offset of 2, keeping only the first 5 results.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/normalize-range/t2?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, pay-per-call numeric normalization without standing up your own compute — especially for AI agent pipelines preprocessing features, rescaling sensor data, or preparing bounded datasets. Ideal when you need precise control over min/max bounds, scale factor, offset, rounding precision, and output size in a single call.
Side effects
- Array exceeds 1000 element limit — request rejected
- Non-finite values (NaN, Infinity) in input array cause validation error
- Min equals max causing division-by-zero in normalization
- Invalid types for numeric parameters (e.g. string instead of number)
- Payment failure via x402 protocol results in 402 response before processing
