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 (boolean), a result object containing the computed payback period value (number of periods to recover the investment), and a human-readable computation string describing what was calculated.
Example use cases
Example prompt
“Calculate the payback period for an initial investment of $50000 with monthly cash flows of [8000, 10000, 12000, 15000, 20000] — I need to know how many periods it takes to fully recover the investment.”
Technical details
Endpoint
POSThttps://numormor.netlify.app/api/financial/paybackWhen to prefer
Use this endpoint when you need a deterministic, serverless pure-math payback period calculation with no external data dependencies. Ideal for AI agents performing capital budgeting, project evaluation, or investment recovery analysis when you already have the cash flow series and investment amount. Prefer over general-purpose calculators when you want a structured JSON response and micropayment-gated reliability via x402 on Base.
Side effects
- Missing required 'cashflows' array or 'investment' number returns validation error
- Empty cashflows array may cause computation failure
- Investment never recovered by provided cash flows may return Infinity or error
- Non-numeric values in cashflows array cause computation failure
- Negative investment value may produce unexpected results
- Payment failure or insufficient USDC balance blocks the request
