Numora Confidence Interval Calculator
x402
Numora Confidence Interval Calculator is a paid API for AI agents from numormo.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).
Computes statistical confidence intervals for a dataset at a specified confidence level (e.g., 95%)

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 'result' containing the computed confidence interval (lower and upper bounds), margin of error, sample mean, and possibly standard error or degrees of freedom; plus a 'computation' string describing what was calculated in plain English, and a 'success' boolean.
Example use cases
Survey result margin of error
“I ran a survey and got these satisfaction scores: [72, 85, 90, 68, 77, 83, 91, 74, 88, 79]. Can you calculate a 95% confidence interval so I know the margin of error on my average score?”
Lab measurement uncertainty
“Here are 8 repeated measurements from my experiment: [5.12, 5.09, 5.14, 5.11, 5.13, 5.10, 5.15, 5.08]. Compute a 99% confidence interval so I understand the uncertainty range around the true value.”
A/B test conversion rate analysis
“My A/B test produced these daily conversion counts: [0.034, 0.041, 0.038, 0.036, 0.043, 0.039]. Give me a 90% confidence interval so I can tell whether the variation is statistically meaningful.”
Technical details
Endpoint
POSThttps://numormo.vercel.app/api/statistics/confidenceWhen to prefer
Choose this endpoint when you need a pure-math, server-side confidence interval computation with no external data dependencies — ideal for agents that have already collected numeric samples and need a fast, reliable statistical interval without setting up a local math library. Particularly suited for micropayment-gated pipelines using x402 on Base. Prefer alternatives if you need confidence intervals for proportions (binomial), survival analysis, or Bayesian credible intervals.
Side effects
- Empty or missing 'data' array returns a validation error
- Data array with fewer than 2 elements may cause division-by-zero or insufficient degrees of freedom
- Invalid confidence level (outside 0–1 range or missing) may default to 0.95 or return an error
- Non-numeric values in the data array will likely cause a computation failure
- Server-side errors return success: false with an error message
