Numora Z-Score Computation API
x402
Numora Z-Score Computation API is a paid API for AI agents from numomo.vercel.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 a success flag, a result object containing the computed z-scores (and likely mean and standard deviation of the input array), and a human-readable computation description string explaining what was calculated.
Example use cases
Outlier detection in test scores
“I have a set of student test scores — [55, 78, 82, 90, 45, 88, 76, 99, 61, 73] — can you compute the z-scores so I can flag which students scored unusually high or low?”
Quality control in manufacturing
“We measured product weights in grams: [500.1, 499.8, 500.3, 501.5, 499.9, 502.1, 500.0, 498.7] — calculate the z-scores so I can identify which measurements are statistically anomalous.”
Financial return normalization
“I have monthly portfolio returns as percentages: [2.1, -0.5, 3.4, 1.2, -1.8, 4.0, 0.7, -0.3, 2.8, 1.5] — compute the z-scores so I can see which months had abnormally high or low performance relative to the average.”
Technical details
Endpoint
POSThttps://numomo.vercel.app/api/statistics/zscoreWhen to prefer
Choose this endpoint when you need pure server-side z-score computation without any external data dependencies — ideal for AI agents that need deterministic, reproducible statistical normalization at low cost ($0.10 USDC). Prefer this over general-purpose code execution environments when you want a reliable, single-purpose math microservice with no setup overhead.
Side effects
- Empty data array returns validation error
- Non-numeric values in array cause computation failure
- Single-element array may cause division-by-zero for standard deviation
- Malformed request body returns 400 error
- Payment not processed results in 402 response
- Very large arrays may cause timeout
