Numora Z-Score Computation
x402
Numora Z-Score Computation is a paid API for AI agents from numnumora.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-13).
Computes z-scores (standard scores) for a dataset, measuring how many standard deviations each value is from the mean
Price / call$0.1

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 the z-scores for each data point along with computed mean and standard deviation, and a computation string describing what was calculated.
Example use cases
Example prompt
“Calculate the z-scores for this dataset: [12, 15, 14, 10, 18, 22, 9, 17] — I want to know how many standard deviations each value is from the mean.”
Technical details
Endpoint
POSThttps://numnumora.vercel.app/api/statistics/zscoreWhen to prefer
Use this endpoint when you need pure server-side z-score computation without installing statistical libraries locally, especially in serverless or lightweight agent environments. Ideal for agents needing fast, dependency-free statistical normalization with micropayment billing.
Side effects
- Missing 'data' field returns validation error
- Empty array or single-element array may produce division-by-zero for standard deviation
- Non-numeric values in the array cause computation failure
- Malformed JSON body returns 400 error
- Payment not included or insufficient USDC returns 402 Payment Required
