Numora IRR (Internal Rate of Return) Calculator
x402
Numora IRR (Internal Rate of Return) Calculator is a paid API for AI agents from numormor.netlify.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).
Computes the Internal Rate of Return (IRR) for a series of cash flows using pure mathematical computation
Price / call$0.1

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 status, a result object containing the computed IRR as a decimal or percentage, and a human-readable computation description explaining what was calculated.
Example use cases
Example prompt
“Calculate the IRR for a project with these cash flows: -10000 at year 0, then 3000, 4000, 4000, and 3500 in the following four years.”
Technical details
Endpoint
POSThttps://numormor.netlify.app/api/financial/irrWhen to prefer
Use this endpoint when you need a pure server-side mathematical IRR computation with no external data dependencies, especially in agentic workflows requiring micropayment-gated financial math. Prefer over spreadsheet tools when you need a reliable API call, and over general-purpose LLM math when precision is required.
Side effects
- No real IRR exists if cash flows never change sign — returns error or NaN
- IRR may not converge if cash flows have multiple sign changes (multiple IRR problem)
- Empty or single-element cashflows array may return validation error
- Non-numeric values in cashflows array cause computation failure
- All-positive or all-negative cash flows have no valid IRR solution
