ONE Engine Numeric Histogram (T5)
x402
ONE Engine Numeric Histogram (T5) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0025/call, status unknown (last checked 2026-10-02).
Computes a histogram over a list of numeric values, with optional binning controls like bin count, min/max range, scaling factor, offset, and decimal digit rounding.

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 bins and the count of input values that fall into each bin, reflecting the configured binning parameters (size, min, max, factor, offset, digits).
Example use cases
Sensor data distribution analysis
“I have 500 accelerometer readings from a device test — can you build a histogram with 15 bins ranging from -10 to 10 so I can see how the values are distributed?”
Score distribution for student grades
“Here are the exam scores for my class of 80 students. Group them into 10 bins from 0 to 100 and tell me the frequency in each bin.”
Financial return bucketing
“I have daily return percentages for a stock over the past year — bin them into 25 buckets between -5 and 5 percent, rounded to 3 decimal places, so I can visualize the distribution.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/histogram/t5?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, cheap, pay-per-call histogram computation without standing up a statistics library or data pipeline. Ideal for autonomous agents that periodically need to summarize numeric distributions — sensor data, financial returns, scores — with configurable bin ranges and rounding, paying fractions of a cent per call over x402 on Base.
Side effects
- Missing required 'values' array returns a 400-level error
- More than 1000 values in the array may be rejected or truncated
- Non-finite numbers (NaN, Infinity) in the values array may cause errors
- Invalid type for 'size' (non-integer) returns a schema validation error
- Insufficient USDC balance or payment failure returns HTTP 402
- Network timeout on the Cloudflare Worker returns 5xx
