Example use cases
Mortgage rate comparison tool
“I'm comparing two mortgage offers — one has a nominal rate of 5.5% compounded semi-annually and another at 5.4% compounded monthly. Can you calculate the effective annual rate for the semi-annual one so I can compare them properly?”
Savings account true yield
“My savings account advertises a 4.8% nominal interest rate compounded daily — what's the actual effective annual rate I'll earn?”
Credit card true cost calculation
“A credit card charges 24% nominal interest compounded monthly. What's the real effective annual interest rate I'm paying on that balance?”

Use this endpoint when you need a quick, cheap ($0.002 USDC) serverless computation of effective annual interest rate from a nominal rate and compounding frequency, without building the formula locally. Suitable for financial comparison workflows, personal finance agents, and educational tools where a lightweight hosted computation is preferred over client-side math.
Side effects
- Missing or non-numeric nominal_rate returns validation error

- periods_per_year of zero or negative causes division-by-zero or invalid computation
- Extremely large periods_per_year values may return floating-point precision edge cases
- Service downtime returns non-200 HTTP response requiring x402 payment retry logic
