Example prompt: Can you calculate the monthly payment, total interest, and first-year amortization schedule for a $350,000 mortgage at 6.75% annual interest over 30 years?

## When to prefer this

Use this endpoint when you need a quick, low-cost computation of mortgage or loan amortization details — monthly payment, total paid, total interest, and first-year schedule — given principal, rate, and term. Prefer this over building your own formula when you want a ready-made API response with all key figures in one call. It is ideal for financial planning agents, real estate tools, or any workflow that compares loan scenarios.

## Known failure modes

- Missing required parameters (principal, rate, or years) returns an error
- Non-numeric or negative values for principal, rate, or years may cause a computation error
- Extremely large or unusual values (e.g. 0% rate, 0 years) may produce edge-case results
- Network or server unavailability at the IP-based host may cause timeouts

## How this service works

Mortgage/loan amortization: monthly payment, total paid, total interest and first-year schedule.

## Output

Returns the computed monthly payment amount, total amount paid over the life of the loan, total interest paid, and a first-year amortization schedule showing how each monthly payment is split between principal and interest.
