Numora Net Present Value (NPV) Calculator
x402
Numora Net Present Value (NPV) Calculator is a paid API for AI agents from numomo.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).
Computes the Net Present Value of a series of cash flows discounted at a given rate, returning the NPV result with a human-readable computation description

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 boolean success flag, a result object containing the computed NPV value, and a computation string providing a human-readable description of what was calculated (e.g. the discount rate used and sum of discounted cash flows).
Example use cases
Project investment feasibility check
“I'm evaluating a capital project that costs $50,000 upfront and is expected to return $15,000 per year for 5 years. Calculate the NPV at a 8% discount rate so I can see if it's worth the investment.”
Startup funding ROI analysis
“Our startup is considering an investment with cash flows of [-200000, 40000, 70000, 90000, 110000, 120000]. Can you compute the NPV at a 12% discount rate to see if it creates value?”
Real estate deal valuation
“I'm looking at a rental property deal with an initial outlay of $300,000 and projected net rental income of $25,000 a year for 10 years. What's the NPV at a 7% discount rate?”
Technical details
Endpoint
POSThttps://numomo.vercel.app/api/financial/npvWhen to prefer
Choose this endpoint when you need a pure server-side NPV computation with no external data dependencies — ideal for AI agents performing financial analysis, capital budgeting, or investment screening where you already have the cash flow series and discount rate. Prefer this over spreadsheet tools or LLM-native math when you need a deterministic, auditable numeric result. Best for scenarios requiring fast, reliable financial math without needing market data or asset price lookups.
Side effects
- Missing required 'rate' field returns validation error
- Missing or empty 'cashflows' array returns validation error
- Non-numeric values in cashflows array cause computation failure
- Rate provided as percentage (e.g. 10) instead of decimal (0.10) may produce unexpected results
- Empty cashflows array may return zero or error
- Network timeout if Vercel cold start is slow
