Example use cases
Example prompt
“What's my full monthly PITI mortgage payment on a $450,000 home with a $90,000 down payment, 6.75% APR, 30-year term, 1.2% property tax, $1,800 annual insurance, $250/month HOA, and no PMI override?”
Technical details
Endpoint
POSThttps://x402toll.com/v1/lending/mortgage-paymentWhen to prefer
Use this endpoint when you need a complete, itemized monthly mortgage cost estimate (PITI) rather than just principal & interest. It automatically handles PMI when the down payment results in LTV > 80%, making it ideal for home-buying affordability analysis, rent-vs-buy comparisons, or financial planning without needing to manually compute each cost component.
Side effects
- Missing required fields (apr, homePrice) returns a validation error
- Negative or zero homePrice/APR returns an error
- APR expressed as a whole number instead of decimal may produce unrealistic results
- LTV calculation assumes downPayment is subtracted from homePrice; incorrect inputs yield incorrect PMI logic
