Payment Engine APIs

Loan Origination API

The Loan Origination API sets the industry standard as the most robust and configurable payment calculation engine available in the market. On top of having over 1,000 different possible interest accrual calendar modifications at your disposal, this API computes the required payment, loan data, and contract disclosure values for a client's defined loan products in each state of operation such as sales tax, fees, credit insurance, and more.

Leasing Origination API

The Leasing Origination API computes the capitalized cost, residual value, and monthly lease payments, including the state-required sales tax and other items needed for Reg. M disclosures. The rent charge can be computed using a money factor, a simple interest rate, or a special method offered by the captive auto lenders.

OriginationPlus API

The OriginationPlus API combines both the Loan Origination API and Compliance API in the same call. This results in precise and compliant payment computations, insurance, fees, ancillary products, and other components of a consumer loan transaction including all Federal Truth In Lending Act (TILA) disclosure requirements.

CarCalcs Suite of APIs

CarCalcs Suite of APIs provides your platform with the tools to effectively manage and compute automotive finance-specific sales tax, registration, and dealer fees for the motor vehicle, RV, Marine, Trailer, and Powersport industries. Also, gain access to lender programs, OEM rebates, and incentives to ensure you are offering the end-users the best price available.

Student Lending API

The Student Lending API computes the federal student lending disclosures. Support includes computing interim (in-school and grace) payments or deferral, graduated repayment, and origination fee calculations. The API will also compute the "single yield rate" deductible charge as required by the IRS for the 1098-E disclosure.

Mortgage API

The Mortgage API supports all mortgage loan types including fixed rate, adjustable rate, graduated payment adjustable rate, buy-downs, equal principal reduction, construction, and construction with permanent financing using monthly payments as well as other payment frequency payments. PMI and FHA insurance are also supported computations within this API.
