Numora Z-Score Computation API
x402
Numora Z-Score Computation API is a paid API for AI agents from numorapoi.orbonomy.xyz, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-13).
Computes the z-score (standard score) for a dataset, returning 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 computed z-scores for each input value (and likely the mean and standard deviation used), 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, 61, 78, 95, 83] so I can see which values are statistical outliers.”
Technical details
Endpoint
POSThttps://numorapoi.orbonomy.xyz/api/statistics/zscoreWhen to prefer
Choose this endpoint when you need a self-contained, dependency-free z-score computation with micropayment access via x402 on Base. Ideal for AI agents needing on-demand statistical normalization without integrating a full data science stack or managing API keys. Best when you need a simple, reliable pure-math computation that returns immediately.
Side effects
- Missing or empty data array returns validation error
- Non-numeric values in data array cause computation failure
- Single-element array may fail or return undefined z-score (no variance)
- Payment of 0.1 USDC via x402 not completed returns 402 Payment Required
- Malformed JSON body returns 400 Bad Request
