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 computed rank value, and a human-readable computation description string explaining what was calculated.
Example use cases
Example prompt
“What's the rank of this matrix: [[1, 2, 3], [4, 5, 6], [7, 8, 9]]?”
Technical details
Endpoint
POSThttps://numorapoi.orbonomy.xyz/api/matrix/rankWhen to prefer
Use this endpoint when an AI agent needs to compute the rank of a matrix without setting up any local computation environment. Ideal for agents operating in stateless or sandboxed environments where running NumPy or MATLAB is not possible. Prefer this over general-purpose code execution when the task is purely matrix rank computation and cost-per-call micropayments are acceptable.
Side effects
- Non-2D array input causes validation error
- Non-numeric values in matrix cause computation failure
- Empty matrix or empty rows trigger error
- Missing required field A returns 400 error
- Oversized matrix may time out or hit compute limits
- Payment failure via x402 returns 402 Payment Required
