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=true, a result object containing the computed simple interest value, and a human-readable computation string describing what was calculated.
Example use cases
Simple interest on personal loan
“I took out a personal loan of $12,000 at an annual interest rate of 7.5% for 4 years. How much simple interest will I owe by the end of the term?”
Interest earned on savings deposit
“I deposited $8,500 into a savings account at 3.2% annual interest. Can you tell me how much simple interest I'll earn over 18 months?”
Short-term business note interest
“We issued a short-term business note for $25,000 at a 5% annual rate for 6 months. What's the total simple interest due when it matures?”
Technical details
Endpoint
POSThttps://numormor.netlify.app/api/financial/simple-interestWhen to prefer
Choose this endpoint when you need a fast, dependency-free computation of simple interest (I = P × r × t) without compound interest or amortization. Ideal for straightforward financial math tasks where the formula is fixed and no external data sources (e.g. live rates) are needed. Prefer over a general-purpose LLM calculation when you want a reliable, auditable numeric result.
Side effects
- Missing required fields (principal, rate, or periods) returns a validation error
- Non-numeric values for rate, periods, or principal cause a bad request error
- Negative principal or rate may return unexpected results if not validated server-side
- Payment failure via x402 micropayment returns a 402 Payment Required response
