Output
Returns computed mortgage figures including estimated monthly payment amount, breakdown of principal vs interest, total cost over the loan term, and potentially an amortization schedule summary based on the provided loan parameters.
Example use cases
First-time homebuyer payment estimate
“I'm looking at a $375,000 house and can put 10% down. What would my monthly mortgage payment be on a 30-year loan at 7.1% interest?”
15 vs 30 year mortgage comparison
“Can you calculate and compare my monthly payments for a $500,000 mortgage at 6.5% interest for both a 15-year and a 30-year term so I can decide which fits my budget?”
Affordability check for budget planning
“If I want to keep my mortgage payment under $2,500 a month and I can get a 30-year loan at 6.8%, what's the maximum home price I should be looking at assuming 20% down?”
Technical details
Endpoint
POSThttps://nexus-api-virid.vercel.app/api/finance/mortgage/calcWhen to prefer
Use this endpoint when an agent needs a quick, pay-per-call mortgage computation without setting up a dedicated financial API key. Ideal for one-off or infrequent mortgage calculations embedded in broader real estate or personal finance workflows. Best suited when the user needs an immediate numeric estimate rather than a full mortgage application or lender-specific quote.
Side effects
- Missing or malformed query input returns a 400 error
- Invalid numeric values (negative loan amount, zero term) may cause computation errors
- Overly vague query string without structured loan parameters may return unhelpful results
- Payment failure via x402 returns 402 status before any computation occurs
- Extremely unusual loan parameters may produce unreliable estimates
