Output
Returns a JSON object containing the computed covariance matrix across the provided datasets, along with a status field indicating success. The matrix captures pairwise covariances between all variables supplied in the input.
Example use cases
Portfolio risk covariance analysis
“I have daily return data for five stocks over the past 30 days. Can you compute the covariance matrix for all of them so I can assess how correlated their risks are?”
ML feature correlation check
“Before training my model, I want to check how my numeric features co-vary. Can you run a covariance matrix on these three feature columns from my dataset and give me back the JSON result?”
Scientific experiment variable analysis
“I've collected measurements for temperature, humidity, and pressure across 20 trials. Can you compute the covariance matrix across those three variables so I can see which pairs move together?”
Technical details
Endpoint
POSThttps://kihustle.tech/agents/api/v1/json-covariance-matrix?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, paid, stateless covariance matrix computation returned as structured JSON without setting up your own statistical library or compute environment. Best suited for lightweight, on-demand statistical analysis within an agent workflow where you pass datasets and immediately receive the matrix result.
Side effects
- Missing or malformed datasets object returns an error
- Non-numeric data in datasets causes computation failure
- Empty dataset object may return a trivial or error result
- Insufficient data points per variable may yield unreliable covariance estimates
- Network or payment processing errors return a 402 or 5xx response
