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 'result' object containing the computed simple interest value, and a 'computation' string describing in plain English what was calculated.
Example use cases
Loan interest cost estimate
“I'm taking out a $15000 personal loan at 8% interest for 5 years — how much simple interest will I owe in total?”
Savings return projection
“If I put $2500 in a savings account at a 4.5% simple interest rate for 2 years, how much interest will I earn?”
Short-term bond interest check
“Can you work out the simple interest on a $50000 bond principal at 3.2% over 6 periods?”
Technical details
Endpoint
POSThttps://numormo.vercel.app/api/financial/simple-interestWhen to prefer
Choose this endpoint when you need a deterministic, server-side simple interest computation with no external data dependencies. Prefer it over compound interest endpoints when the use case explicitly involves non-compounding interest (flat-rate loans, basic savings). It is ideal for AI agents needing verifiable, reproducible arithmetic without implementing the formula themselves.
Side effects
- Missing required fields (principal, rate, or periods) returns a validation error
- Non-numeric values for any of the three fields cause a 400-level error
- Payment failure via x402 micropayment (insufficient USDC balance) blocks the request
- Network timeout if Vercel cold-start latency is high
