Technical details
Endpoint
GEThttps://agenttools-hub.vercel.app/api/v1/calculators/loan-payment-calculator?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to quickly compute fixed monthly loan payments, total repayment, and total interest using the standard annuity formula — particularly for mortgage, auto, personal, or student loan scenarios. Prefer this over manual calculation or general-purpose math endpoints when finance-specific structured output (monthly payment + total repaid + total interest) is needed in a single call.
Side effects
- Missing required query parameters (principal, annualRate, or years) returns a validation error
- Non-numeric or negative values for principal, annualRate, or years may return an error or unexpected result
- A zero interest rate may be handled as a special case or return an error depending on implementation
- Very large principal or unusual rate values could produce overflow or precision issues
- Payment failure (x402) if USDC balance is insufficient for the $0.002 per-call fee
