Numora Chi-Square Test Computation
x402
Numora Chi-Square Test Computation is a paid API for AI agents from numorapoi.orbonomy.xyz, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-14).
Performs a chi-square goodness-of-fit or independence test given 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 flag, a human-readable computation description, and a result object containing the chi-square statistic, degrees of freedom, p-value, and whether the null hypothesis is rejected at standard significance levels.
Example use cases
Example prompt
“Run a chi-square goodness-of-fit test on these observed counts [50, 30, 20] against expected counts [40, 35, 25] and tell me the chi-square statistic and p-value.”
Technical details
Endpoint
POSThttps://numorapoi.orbonomy.xyz/api/statistics/chisquareWhen to prefer
Choose this endpoint when you need a pure server-side chi-square computation with no external library dependencies, especially in agent pipelines requiring micropayment-based serverless math and you already have observed frequency counts (and optionally expected frequencies) ready as arrays.
Side effects
- Missing observed array returns 400 validation error
- Mismatched lengths between observed and expected arrays causes computation error
- Non-numeric values in arrays cause parsing failure
- Negative frequency values may produce invalid results
- Zero expected values cause division-by-zero errors in chi-square formula
