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 (always true on success), a 'result' object containing the computed correlation coefficient and related statistics, and a 'computation' string describing in plain English what was calculated.
Example use cases
Sales vs. ad spend correlation
“I have monthly sales figures [5000, 5800, 6200, 7100, 8000] and monthly ad spend [1000, 1200, 1300, 1500, 1700] — can you calculate the correlation between them so I know how closely ad budget drives revenue?”
Climate data relationship check
“Run a correlation between these temperature readings [15, 18, 22, 27, 30] and ice cream sales counts [200, 280, 350, 420, 510] to see how strongly heat drives sales.”
Portfolio returns correlation analysis
“Can you compute the correlation between stock A's weekly returns [0.02, -0.01, 0.03, 0.015, -0.005] and stock B's returns [0.018, -0.008, 0.025, 0.012, -0.003] to assess how diversified my portfolio is?”
Technical details
Endpoint
POSThttps://numomo.vercel.app/api/statistics/correlationWhen to prefer
Use this endpoint when you need a fast, serverless, dependency-free computation of the statistical correlation between two numeric arrays without setting up a local math library. Ideal for AI agents needing a lightweight math microservice with per-call micropayment pricing on Base, especially in environments where installing scipy or numpy is not feasible.
Side effects
- Arrays x and y have different lengths — returns an error
- Non-numeric values in input arrays cause computation failure
- Empty arrays provided — returns validation error
- Missing required field x or y — returns 400-level error
- Micropayment failure via x402 protocol prevents request from being processed
