ONE Engine Moving Average (T2)
x402
ONE Engine Moving Average (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 moving average over a sequence of up to 1000 numeric values with optional scaling, clamping, rounding, 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 computed moving average series derived from the input numeric array, reflecting the configured window size, optional min/max clamping, decimal rounding precision, multiplicative factor, and additive offset.
Example use cases
Smooth stock price series
“I have a list of daily closing prices for the past 30 days: [150, 152, 148, 155, 160, 158, 162, 165, 163, 170, 168, 175, 172, 178, 180, 179, 183, 185, 182, 188, 190, 187, 192, 195, 193, 198, 200, 197, 202, 205]. Can you compute a 7-day moving average over them, rounded to 2 decimal places?”
Smooth IoT temperature sensor readings
“I'm getting noisy temperature readings from my sensor: [22.1, 21.8, 23.5, 22.9, 24.1, 23.7, 25.0, 24.5, 23.8, 24.2, 25.1, 24.8]. Can you apply a 3-period moving average to smooth them out, clamping results between 20 and 30 degrees?”
Normalize and average sales metrics
“Here are my weekly sales figures scaled weirdly: [1050, 1200, 980, 1300, 1150, 1400, 1250, 1100, 1350, 1500]. Can you compute a 4-week moving average, apply a factor of 0.001 to convert to thousands, and round to 1 decimal place?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/moving-average/t2?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call moving average computation without spinning up your own math infrastructure. It is particularly useful for AI agents that need on-demand numeric smoothing of time series, sensor data, or financial series, especially when combined with clamping and rounding options in a single call. Prefer it over general-purpose compute services when cost-efficiency at micro-scale ($0.0007/call) and simplicity matter.
Side effects
- Array exceeds 1000 values — request rejected
- Non-finite numbers (NaN, Infinity) in the values array cause errors
- Window size (size) larger than the input array length may produce empty or partial results
- Payment failure via x402 protocol blocks request
- Invalid types for numeric parameters cause schema validation errors
