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' (boolean), 'result' (object containing the computed IRR value as a decimal or percentage), and 'computation' (a human-readable description of what was computed, e.g. 'Internal rate of return for 5 cash flows').
Example use cases
Example prompt
“Calculate the IRR for an investment with these cash flows: -100000 initial outlay, then 30000, 40000, 50000, and 20000 over the following four years.”
Technical details
Endpoint
POSThttps://numorapoi.orbonomy.xyz/api/financial/irrWhen to prefer
Choose this endpoint when you need a fast, dependency-free computation of IRR from a cash flow array without setting up a financial library or runtime. Ideal for AI agents performing capital budgeting, investment comparison, or project evaluation that need a pure-math backend with micropayment pricing and no API key management overhead.
Side effects
- No real IRR exists (all-positive or all-negative cash flows yield no root) — returns error or NaN
- Non-convergence if the iterative solver fails to find a root within tolerance — may return error
- Empty or single-element cashflows array — likely returns validation error
- Malformed input array (non-numeric values) — returns 400 or error response
- Payment required (HTTP 402) if x402 micropayment header is missing or invalid
