Numora Chi-Square Statistics Endpoint
x402
Numora Chi-Square Statistics Endpoint 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 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=true, a result object containing the chi-square statistic, degrees of freedom, p-value, and possibly critical value or significance flag, plus a human-readable computation string describing what was calculated.
Example use cases
Example prompt
“Run a chi-square test on my observed frequencies [90, 60, 104, 95, 62, 89] against expected frequencies [80, 80, 80, 80, 80, 80] and tell me the chi-square statistic and whether the result is statistically significant.”
Technical details
Endpoint
POSThttps://numnumora.vercel.app/api/statistics/chisquareWhen to prefer
Choose this endpoint when you need a serverless, zero-dependency chi-square computation with micropayment pricing — ideal for AI agents that need statistical hypothesis testing on frequency data without setting up a local math library or calling a heavyweight analytics platform. Best for single-call, on-demand goodness-of-fit or independence tests within automated pipelines.
Side effects
- Missing required 'observed' array returns a 400 or error response
- Mismatched lengths between observed and expected arrays may cause computation error
- Empty arrays or non-numeric values may produce invalid results
- observed array with all zeros may result in division-by-zero or NaN
- Network or server timeout returns 5xx error
