ONE Engine Moving Average Calculator
x402
ONE Engine Moving Average Calculator is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-02).
Computes a moving average over an array of numeric values with configurable window size, scaling, and clamping options.

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 smoothed moving average series derived from the input array, with values optionally scaled, offset, clamped to min/max bounds, and rounded to the specified number of decimal digits.
Example use cases
Smooth noisy stock price data
“I have 50 daily closing prices for a stock and want to smooth them out — calculate a 7-day moving average over these values and round each result to 4 decimal places: [142.3, 143.1, 141.8, ...]”
Sensor telemetry noise reduction
“These are temperature readings from an IoT sensor — run a moving average with a window of 10 over all 200 readings, clamp the output between -40 and 125, and give me the smoothed series.”
Normalize and smooth signal for chart display
“Take this array of 500 raw audio amplitude values, compute a moving average with a window size of 20, apply a scale factor of 0.5 and an offset of 128 to normalize them for display, and round to 1 decimal place.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/moving-average/t6?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-call moving average computation without hosting your own math service — especially useful for AI agents that sporadically need signal smoothing, financial rolling averages, or sensor data preprocessing at low cost ($0.004/call) via x402 on Base.
Side effects
- Input array exceeds 1000 elements — request rejected
- Non-finite or NaN values in the input array cause computation failure
- Window size (size) larger than input array length may return empty or partial results
- Invalid type for parameters (e.g. non-integer for digits) returns a 400 error
- Payment not included or insufficient USDC results in 402 Payment Required
