How this service works
Net present value and internal rate of return for a cash-flow series (index 0 = today, usually a negative outlay), plus the profitability index and an accept/reject call.
Output
Returns the net present value (NPV) in currency units, the internal rate of return (IRR) as a percentage, the profitability index (PI), and an accept/reject recommendation based on whether NPV is positive and IRR exceeds the discount rate.
Example use cases
Example prompt
“Can you calculate the NPV and IRR for this project — the cash flows are -50000 today, then 15000, 18000, 22000, and 20000 over the next four years — using a 10% discount rate, and tell me whether we should accept it?”
Technical details
Endpoint
POSThttps://x402toll.com/v1/investing/npv-irrWhen to prefer
Use this endpoint when you need a complete capital budgeting analysis — NPV, IRR, profitability index, and a clear accept/reject call — in a single API call. Prefer it over generic calculators when you need the profitability index and a structured go/no-go decision alongside the standard DCF metrics. Ideal for evaluating real estate investments, business projects, or any multi-period cash flow scenario where you have a known discount/hurdle rate.
Side effects
- Fewer than 2 cash flows provided — schema requires minItems: 2
- More than 600 cash flows provided — schema enforces maxItems: 600
- IRR cannot be computed if cash flows never change sign (no internal rate exists), resulting in a null or error for IRR
- Non-numeric values in the cashFlows array cause a validation error
- Missing or malformed request body returns a 400-level error
- Payment not included or insufficient USDC causes x402 payment-required response
