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 boolean success flag, a result object containing the computed correlation coefficient between the two input arrays, and a human-readable computation description string explaining what was calculated.
Example use cases
Correlation between sales and marketing spend
“I have monthly sales figures and marketing spend for the past year — can you check how correlated those two series are using Numora? I want to know if there's a strong linear relationship before I make budget decisions.”
Check if temperature affects energy usage
“Here are daily average temperatures and our building's energy consumption readings for the last 30 days. Run a correlation on them using Numora's math API so I can see how strongly temperature is driving our power usage.”
Measure stock price co-movement
“I've got daily closing prices for two stocks over the past quarter. Use Numora to compute the correlation coefficient between them — I want to know how closely they move together before I consider them as a hedge pair.”
Technical details
Endpoint
POSThttps://numorapoi.orbonomy.xyz/api/statistics/correlationWhen to prefer
Choose this endpoint when you need a fast, dependency-free, server-side statistical correlation computation without setting up a local math library. Ideal for AI agents that need pure math results on-demand, especially when processing two parallel numeric datasets to measure their linear relationship. Prefer over general-purpose compute services when you want a simple, paid-per-call micropayment model with no API key management.
Side effects
- Mismatched array lengths — x and y must have the same number of elements
- Empty arrays provided — computation requires at least two data points
- Non-numeric values in arrays causing type errors
- Arrays with zero variance (all identical values) causing division-by-zero in correlation formula
- Payment failure via x402 micropayment protocol blocks the request
- HTTP 402 returned if USDC payment is not completed before processing
