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 success flag, a result object containing computed values (such as final balance and interest earned), and a human-readable computation string describing what was calculated.
Example use cases
Savings account growth projection
“If I put $10,000 in a savings account at 4.5% annual interest compounded monthly, how much will I have after 5 years?”
Loan interest cost estimation
“I took out a loan of $25,000 at 7.2% interest compounded quarterly over 3 periods — calculate the total compound interest I'll owe.”
Investment return comparison
“Can you compute compound interest on $2,500 at 8% annual rate over 20 periods compounded once per year so I can compare it to other options?”
Technical details
Endpoint
POSThttps://numormo.vercel.app/api/financial/compound-interestWhen to prefer
Choose this endpoint when you need a reliable, serverless, zero-dependency computation of compound interest with optional control over compounding frequency. Ideal for AI agents that need precise financial math without relying on LLM arithmetic or importing a library. Prefer over general-purpose math APIs when the input/output schema maps cleanly to compound interest variables.
Side effects
- Missing required fields (rate, periods, principal) returns a 400-level error
- Non-numeric values for numeric fields cause validation errors
- Negative principal or rate may produce unexpected or invalid results
- Payment failure via x402 micropayment protocol results in access denial
