ONE Engine Numeric Histogram
x402
ONE Engine Numeric Histogram is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0065/call, status unknown (last checked 2026-10-02).
Computes a frequency histogram over an array of numeric values with configurable bin count, range, scaling, and rounding.

How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a histogram object with bin boundaries and frequency counts for each bucket, covering the specified or auto-detected numeric range across the requested number of bins, with optional scaling and offset applied.
Example use cases
Sensor data distribution analysis
“I have 500 temperature readings from my IoT devices — can you bucket them into 15 bins between -10 and 50 degrees and show me the frequency distribution?”
Financial returns histogram
“Here are 1000 daily return values from my portfolio — group them into 25 bins from -0.05 to 0.05 and give me the histogram so I can see how the returns are distributed.”
Age distribution bucketing
“I've got a list of 300 customer ages — can you compute a histogram with 10 bins from 18 to 80 so I can see which age groups are most common?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/histogram/t7?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-call histogram computation over a numeric array without standing up your own statistics infrastructure. Ideal for autonomous agents that occasionally need to summarize distributions on demand at very low cost ($0.0065/call) without managing API keys or subscriptions. If you need full statistical moments (mean, variance, skew) rather than bin counts, look for a stats endpoint instead.
Side effects
- Array exceeds 1000 elements — rejected with error
- Non-finite values (NaN, Infinity) in input array — may cause computation error
- min >= max when both specified — invalid range error
- Payment not included or insufficient — 402 Payment Required
- Malformed JSON body — 400 Bad Request
