ONE Engine Z-Score (t5) Calculator
x402
ONE Engine Z-Score (t5) Calculator 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 z-scores for an array of numeric values using the t5 method, returning standardized scores indicating how many standard deviations each value is from the mean.

How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing z-score values for each input number, representing how many standard deviations each value lies from the mean of the provided array. May include additional statistical metadata depending on optional parameters like factor, offset, min, max, size, and digits (rounding precision).
Example use cases
Anomaly detection in sensor data
“I have a batch of temperature sensor readings — [98.6, 99.1, 98.9, 104.2, 98.7, 99.0, 97.8] — can you z-score normalize them using the t5 method with 2 decimal digits so I can flag anything more than 2 standard deviations out?”
Preprocessing features for ML model
“Before feeding these exam scores into my model, I need to standardize them with z-scores using the t5 approach — here are the values: [67, 72, 85, 90, 55, 78, 82, 60, 95, 70]. Give me 4 digits of precision.”
Comparing sales performance across regions
“I want to compare how each region's sales figures deviate from the average — can you run z-score normalization with the t5 method on these numbers: [432000, 518000, 290000, 675000, 401000, 557000]?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/numeric/z-score/t5?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, pay-per-call z-score standardization of numeric arrays without standing up your own statistical compute infrastructure. Ideal for AI agents doing lightweight statistical preprocessing, anomaly detection, or normalization as part of a larger pipeline, especially when integrated with x402 micropayment flows on Base. Prefer this over rolling your own when you need configurable rounding (digits), scaling (factor), and shifting (offset) in a single call.
Side effects
- Missing required 'values' array returns validation error
- Array exceeding 1000 elements rejected
- Non-finite numbers (NaN, Infinity) in the values array cause failure
- Payment not included or insufficient USDC triggers 402 response
- Empty array may result in division-by-zero or undefined z-scores
- Non-numeric values in array cause type errors
