Numora Chi-Square Computation
x402
Numora Chi-Square Computation is a paid API for AI agents from numormor.netlify.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).
Computes the chi-square statistic from observed (and optionally expected) frequency arrays

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 chi-square statistic, degrees of freedom, and p-value, plus a human-readable computation description string explaining what was calculated.
Example use cases
Example prompt
“Run a chi-square goodness-of-fit test on these observed counts [10, 20, 30, 40] against these expected counts [25, 25, 25, 25] and tell me the test statistic and whether the difference is significant.”
Technical details
Endpoint
POSThttps://numormor.netlify.app/api/statistics/chisquareWhen to prefer
Use this endpoint when you need a fast, dependency-free chi-square computation without setting up a local statistics library. Ideal for AI agents doing quick hypothesis tests on categorical data, goodness-of-fit checks, or independence tests where micropayment-per-call economics are acceptable.
Side effects
- Missing required 'observed' array returns validation error
- Mismatched lengths between observed and expected arrays cause computation error
- Non-numeric values in arrays cause parse/type errors
- Empty arrays return error or undefined result
- Payment failure (x402) blocks request if USDC balance insufficient
