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 boolean, a result object containing the sampled subset of the input data, and a human-readable computation string describing what was computed. The result reflects the selected sample indices or values depending on the sampling method chosen.
Example use cases
Bootstrap resampling for confidence intervals
“I have this list of 100 sales figures and I need to bootstrap resample 80 of them to estimate a confidence interval — can you draw a bootstrap sample for me? Here's the data: [234, 187, 445, 312, 567, 289, 178, 423, 345, 512, 267, 389, 156, 478, 321, 234, 567, 412, 289, 178, 445, 323, 512, 267, 389, 156, 478, 321, 234, 567, 412, 289, 178, 445, 323, 512, 267, 389, 156, 478, 321, 234, 567, 412, 289, 178, 445, 323, 512, 267, 389, 156, 478, 321, 234, 567, 412, 289, 178, 445, 323, 512, 267, 389, 156, 478, 321, 234, 567, 412, 289, 178, 445, 323, 512, 267, 389, 156, 478, 321, 234, 567, 412, 289, 178, 445, 323, 512, 267, 389, 156, 478, 321, 234, 567, 412, 289, 178, 445, 323]”
Systematic sampling from survey responses
“I have 500 survey response scores and need to take a systematic sample of 50 of them evenly spaced across the dataset. The data starts: [82, 74, 91, 55, 63, 78, 88, 47, 95, 60 ...] — please use systematic sampling to pick 50 values.”
Simple random sample for A/B testing
“Can you randomly draw 20 user IDs from this list of 150 candidates to assign to the treatment group? Use simple random sampling. The IDs are: [1001, 1002, 1003, 1004, 1005, 1006, 1007, 1008, 1009, 1010, 1011, 1012, 1013, 1014, 1015, 1016, 1017, 1018, 1019, 1020, 1021, 1022, 1023, 1024, 1025, 1026, 1027, 1028, 1029, 1030, 1031, 1032, 1033, 1034, 1035, 1036, 1037, 1038, 1039, 1040, 1041, 1042, 1043, 1044, 1045, 1046, 1047, 1048, 1049, 1050]”
Technical details
Endpoint
POSThttps://numormo.vercel.app/api/statistics/samplingWhen to prefer
Choose this endpoint when you need a pure math, dependency-free statistical sampling computation on a known dataset and do not need database access, external data fetching, or ML-based sample generation. Prefer it over custom code execution when you need auditable, consistent sampling logic via API with micropayment-based access. Best for agents performing statistical analysis pipelines that require sampling as an intermediate step.
Side effects
- n exceeds dataset length for non-bootstrap methods — returns error or unexpected behavior
- invalid method enum value — request rejected or defaults used
- empty data array — computation fails with no items to sample
- n is zero or negative — invalid sample size error
- data array contains non-numeric values when numeric computation is expected
