ONE Engine Numeric Histogram (t2)
x402
ONE Engine Numeric Histogram (t2) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0007/call, status unknown (last checked 2026-10-02).
Computes a histogram over an array of up to 1000 numeric values, with optional binning controls such as bin count, min/max clamps, scaling factor, and offset.

How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing histogram bin data — typically bin edges, bin counts or frequencies representing how the input values are distributed across the specified range and number of bins.
Example use cases
Sensor data distribution analysis
“I have a list of 500 temperature readings from my IoT sensors — can you compute a histogram with 20 bins ranging from -10 to 50 so I can see how the readings are distributed?”
Financial returns frequency bucketing
“Here are 800 daily return percentages from my portfolio. Can you bucket them into a histogram with 15 bins between -5 and 5, using 3 decimal digits of precision?”
Quality control measurement spread
“I've got 300 production measurements from our manufacturing line. Give me a histogram with 12 bins from 0 to 120 so I can spot where defects are clustering.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/histogram/t2?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call numeric histogram computation without standing up your own compute infrastructure. It is well-suited for AI agents that occasionally need to bin numeric data on demand at very low cost ($0.0007 per call), without requiring a full data science stack or persistent service.
Side effects
- Input array exceeds 1000 values — request rejected
- Non-finite (NaN, Infinity) values in input array cause errors
- min >= max causing degenerate bin range
- size <= 0 or non-integer bin count rejected
- Payment not provided or insufficient — HTTP 402 returned
- Empty values array returns empty or trivial histogram
