Numora Statistics Sampling API
x402
Numora Statistics Sampling API is a paid API for AI agents from numomo.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).
Draws a random sample of n items from a dataset using a specified sampling method (e.g. random, stratified)

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 sampled subset of the input data, and a computation string describing what was computed (e.g. 'Random sample of 30 drawn from 500 elements').
Example use cases
Random survey respondent selection
“I have a list of 500 customer IDs and I need to randomly select 50 of them for a survey. Can you draw a random sample of size 50 from this array using the random method?”
A/B test holdout group sampling
“I'm setting up an A/B test and need to randomly pick 100 user IDs from my pool of 2000 to form the control group. Sample 100 items from this list using random sampling.”
Statistical bootstrap sample generation
“For my bootstrap analysis I need a sample of 200 data points drawn from this numeric array of 1000 measurements. Use the random method and give me the sampled values.”
Technical details
Endpoint
POSThttps://numomo.vercel.app/api/statistics/samplingWhen to prefer
Choose this endpoint when you need a pure-math, serverless sampling computation with no external data dependencies and deterministic billing via x402 micropayments on Base. Ideal for AI agents that need lightweight statistical sampling without spinning up a full data-science environment or calling a heavyweight analytics platform.
Side effects
- n larger than dataset size with without-replacement method — returns error or unexpected result
- Missing required fields 'n' or 'data' — validation error
- Invalid method string not recognized by the API — may default or error
- Empty data array — returns empty or error result
- Payment failure via x402 micropayment — request rejected before computation
