Numora Z-Score Calculator
x402
Numora Z-Score Calculator is a paid API for AI agents from numormor.netlify.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).
Computes the z-score (standard score) for a dataset, indicating how many standard deviations each value is from the mean

How this service works
100 pure math computation endpoints for AI agents. Statistics, financial math, linear algebra, equation solving, calculus, number theory, sequence generation, and unit conversions. Zero external dependencies. x402 micropayments on Base.
Output
Returns a JSON object with success=true, a result object containing z-score values for each data point (and likely mean and standard deviation), and a human-readable computation string describing what was calculated.
Example use cases
Example prompt
“Calculate the z-scores for this dataset: [72, 85, 90, 68, 95, 78, 82, 74, 88, 91] — I want to know which values are more than 1 standard deviation from the mean.”
Technical details
Endpoint
POSThttps://numormor.netlify.app/api/statistics/zscoreWhen to prefer
Choose this endpoint when you need serverless, dependency-free z-score computation paid per-call via crypto micropayments on Base, without spinning up a statistics library or data science environment. Ideal for AI agents that need lightweight, on-demand statistical standardization without maintaining a math backend.
Side effects
- Missing required 'data' array field returns validation error
- Empty array or single-element array may cause division-by-zero or undefined standard deviation
- Non-numeric values in the data array may cause computation failure
- Payment failure via x402 micropayment returns 402 Payment Required
- Array with zero variance (all identical values) causes division by zero for z-score
