Returns a JSON object with a boolean success flag, a result object containing the computed NPV value, and a human-readable computation string describing what was calculated.
Example use cases
Example prompt
“Calculate the net present value of a project with a discount rate of 8% and cash flows of [-50000, 15000, 18000, 22000, 20000, 17000] — I want to know if this investment makes financial sense.”
Technical details
Endpoint
POSThttps://numorapoi.orbonomy.xyz/api/financial/npvWhen to prefer
Use this endpoint when you need a fast, dependency-free, server-side NPV computation without invoking a general-purpose code interpreter or spreadsheet tool. Ideal for AI agents performing financial analysis, capital budgeting, or investment evaluation where a lightweight micropayment-gated math API is acceptable and no external data sources are required.
Side effects
- Missing required field 'rate' returns a validation error
- Missing required field 'cashflows' returns a validation error
- Non-numeric rate value causes a type error
- Empty cashflows array may return zero or an error
- Payment not provided or insufficient USDC causes x402 payment-required response
- Malformed JSON body returns a 400 bad request
