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' field, a 'computation' string describing what was calculated in human-readable form, and a 'result' object containing the computed simple interest values (typically the interest amount and possibly total amount due).
Example use cases
Loan interest estimation for borrower
“I'm taking out a $15,000 personal loan at a flat interest rate of 8% per year for 3 years — how much simple interest will I owe in total?”
Savings account interest projection
“If I deposit $2,500 in an account offering 4.5% simple interest per year, how much interest will I have earned after 2 years?”
Short-term trade credit calculation
“A supplier is offering me 90-day trade credit on $50,000 at a simple interest rate of 0.5% per period — can you calculate the total interest cost for 3 periods?”
Technical details
Endpoint
POSThttps://numomo.vercel.app/api/financial/simple-interestWhen to prefer
Use this endpoint when you need a quick, dependency-free computation of simple interest (non-compounding) for a known principal, rate, and number of periods. Prefer it over compound interest or amortization endpoints when the financial product explicitly uses flat/simple interest, such as short-term loans, trade credit, or basic savings instruments. It is ideal for AI agents needing deterministic, serverless math without calling a general-purpose LLM or spreadsheet tool.
Side effects
- Missing required fields (rate, periods, or principal) returns a 400-level error
- Non-numeric values for rate, periods, or principal cause a validation failure
- Negative principal or rate values may produce unexpected or erroneous results
- Payment failure via x402 micropayment protocol results in a 402 Payment Required error
- Service unavailability on Vercel hosting may cause intermittent 503 errors
