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 success flag, a human-readable computation description, and a result object containing the t-statistic, p-value, degrees of freedom, and typically a conclusion about whether the means are significantly different at standard confidence levels.
Example use cases
A/B test conversion rate analysis
“I ran an experiment where control group session times were [120, 135, 118, 142, 130] seconds and the treatment group was [145, 160, 138, 155, 162] seconds. Can you do a t-test to tell me if the new feature actually made a statistically significant difference?”
Clinical trial outcome comparison
“I have pain scores for patients on Drug A — [3.2, 4.1, 3.8, 2.9, 3.5] — and Drug B — [5.6, 6.1, 5.4, 5.9, 6.3]. Run a t-test and tell me if there's a real difference between the two treatments.”
Quality control batch testing
“Our first manufacturing batch had defect counts of [2, 3, 1, 4, 2, 3] and the second batch after process changes had [1, 1, 2, 0, 1, 2]. Can you t-test these to see if the process change made a statistically meaningful improvement?”
Technical details
Endpoint
POSThttps://numomo.vercel.app/api/statistics/ttestWhen to prefer
Choose this endpoint when you need a serverless, dependency-free two-sample t-test with micropayment billing per call — ideal for AI agents that need on-demand statistical significance testing without managing a Python/R runtime, spinning up a data science environment, or paying for a heavy analytics platform subscription.
Side effects
- Empty sample arrays cause computation errors
- Non-numeric values in arrays return validation errors
- Arrays with only one element may cause degrees-of-freedom issues
- Mismatched extremely large arrays may time out
- Payment failure (402) if x402 micropayment not properly set up
