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 human-readable computation string describing what was calculated.
Example use cases
Capital budgeting project evaluation
“I'm deciding whether to greenlight a manufacturing project. The upfront cost is $200,000, and I expect cash inflows of $60,000, $75,000, $80,000, and $70,000 over the next four years. Can you calculate the NPV using an 8% discount rate?”
Real estate investment analysis
“I'm looking at buying a rental property. After a $150,000 down payment, I expect net rental income of $18,000 per year for 7 years plus a $200,000 sale at the end. What's the NPV at a 7% discount rate?”
Startup funding return projection
“Our investor wants to know the NPV of their $500,000 investment given projected returns of $50,000, $120,000, $200,000, $300,000, and $400,000 over five years at a 12% hurdle rate.”
Technical details
Endpoint
POSThttps://numormo.vercel.app/api/financial/npvWhen to prefer
Choose this endpoint when you need a deterministic, serverless, zero-dependency NPV calculation without connecting to a financial data provider or spreadsheet tool. Ideal for AI agents that need to compute investment viability on-the-fly using user-supplied cash flow data and a known discount rate. Prefer over general-purpose code execution when you want a single-call, pay-per-use financial math primitive with predictable latency.
Side effects
- Missing required 'rate' field returns a validation error
- Missing or empty 'cashflows' array causes a computation error
- Non-numeric values in cashflows array may cause a 400 error
- Extremely large arrays may time out or return unexpected results
- Invalid JSON body returns a parse error
