Not financial advice — just exact arithmetic on the inputs you give it.","url":"https://x402.forgemesh.io/mortgage-calculator","method":"POST","headers":{},"bodySchema":{"type":"object","properties":{"final":{"type":"string"},"years":{"type":"string"},"initial":{"type":"string"},"principal":{"type":"string"},"calculation":{"type":"string","description":"compound_interest | loan_payment | roi"},"compounds_per_year":{"type":"string"},"annual_rate_percent":{"type":"string"}}},"responseSchema":{"type":"json","example":{"total_interest":382632.9,"monthly_payment":1896.2}},"example":null,"exampleRequest":null,"tags":["x402"],"displayCostAmount":"0.002","displayCostAsset":"USDC","priceDynamic":false,"priceHint":null,"priceStatus":"priced","priceSource":"probe","requiresHandshake":false,"reviewCount":0,"rating":{"score":"0.00","successRate":"0.00","reviews":0,"stars":null,"state":"unrated"},"availabilityStatus":"unknown","priceObserved":null,"sessionDeposit":null,"pricing":{"kind":"static","summary":"$0.002/call","primary":{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.002","per":"call","confidence":"exact"},"accepted":[{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.002","per":"call","confidence":"exact"}]},"paymentMethods":[{"uid":"pm_VyFIhqAt2IWE9McEcSSD0","protocol":"x402","methodType":"crypto","chain":"base","mode":"charge","costAmount":"0.002","costPer":"request","priority":0,"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","unit":"request","depositMicros":null,"planRef":null}],"brandName":null,"brandSlug":null,"brandBaseUrl":null,"brandDocsUrl":null,"whatItDoes":"Calculates exact monthly payment, total amount paid, and total interest owed for a mortgage or loan given principal, annual rate, and term","exampleAgentPrompt":"Can you calculate the exact monthly payment, total paid, and total interest for a $450,000 mortgage at 6.75% annual interest over 30 years?","exampleUseCases":null,"resultDescription":"Returns the exact monthly payment amount, the total amount paid over the full loan term, and the total interest owed — computed arithmetically from the provided principal, annual rate, and term inputs.","failureModes":["Missing required fields (principal, annual_rate_percent, years) return an error or zero/null result","Non-numeric string inputs may cause calculation errors","Very unusual term lengths or edge-case rates (0% or negative) may produce unexpected results","The calculation type enum must match one of: compound_interest, loan_payment, roi — wrong values may return incorrect calculation"],"whenToPreferThis":"Use this endpoint when you need exact, deterministic arithmetic for mortgage or loan payment calculations — especially for home-buying estimates, amortization planning, or any personal finance agent that requires precise numbers rather than approximations.
