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 T3 moving average output — typically an array of smoothed numeric values corresponding to the input series, with leading values omitted or null during the warm-up period, formatted to the requested decimal precision.
Example use cases
Technical indicator for trading bot
“I have a list of 200 daily closing prices for a stock — can you compute the T3 moving average with a period of 14 and a factor of 0.618, rounded to 2 decimal places? I want to use it as a trend signal.”
Smoothing IoT sensor data
“I'm getting noisy temperature readings from a sensor every minute — here are the last 100 values. Can you apply a T3 moving average with window size 10 and factor 0.5 to smooth out the noise?”
Backtesting signal generation
“For these 500 historical price values, calculate the T3 moving average with size 21 and factor 0.7, clamping results between 0 and 10000, so I can backtest a crossover strategy.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/moving-average/t3?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a low-latency, pay-per-call T3 triple exponential moving average computation without hosting your own math library. It is ideal for autonomous agents that need on-demand technical analysis indicators, especially in x402-enabled on-chain or crypto-adjacent workflows on Base. Prefer this over general-purpose EMA endpoints when T3's superior lag reduction and smoothness are required for trading signals or sensor data.
Side effects
- Input array exceeds 1000 elements — request will be rejected
- Non-finite values (NaN, Infinity) in the values array cause computation failure
- Invalid or missing 'values' field returns a 400-level error
- Payment not attached or insufficient USDC balance causes 402 Payment Required
- Factor or size values outside valid ranges may produce unexpected results
