ONE Engine Numeric Histogram (Top-10)
x402
ONE Engine Numeric Histogram (Top-10) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-02).
Computes a histogram over an array of up to 1000 numeric values, returning the top-10 most frequent bins with optional min/max range, bin count, rounding, scaling, and offset controls.

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 top-10 histogram bins derived from the input numeric array, each bin representing a value range and its frequency count, shaped by any supplied min/max bounds, bin count, rounding digits, scale factor, and offset.
Example use cases
Sensor data distribution summary
“I have 800 temperature sensor readings ranging roughly from -10 to 50 degrees. Can you bucket them into 25 bins and show me which 10 ranges appear most frequently, rounded to 1 decimal place?”
E-commerce price range analysis
“Here are the prices of 600 products in my catalog. Split them into 15 bins between $0 and $500 and give me the top 10 most populated price ranges so I can see where my inventory is concentrated.”
Response time profiling
“I've got a list of 1000 API response times in milliseconds. Compute a histogram with 30 bins from 0 to 3000ms and tell me the top 10 most common latency buckets, scaled by a factor of 0.001 to convert to seconds.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/histogram/t10?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, pay-per-call numeric histogram focused on the top-10 most populated bins from a raw numeric array, especially in agent workflows on Base where x402 micropayments are already in use. Prefer it over full statistical libraries when you only need a ranked bin distribution without a full stats package or persistent storage.
Side effects
- Array contains more than 1000 values — request rejected or truncated
- Non-finite values (NaN, Infinity) in the array cause computation errors
- min >= max produces degenerate or empty bins
- size <= 0 or negative bin count returns an error
- Payment not submitted or insufficient USDC balance returns HTTP 402
