FinCalc API

Send a calculator its inputs and get a calculated result back. Each calculator is one endpoint, POST /v2/calculators/{slug}, documented in the API Reference.

Requests are authenticated with an API key sent as a bearer token:

Code
POST /v2/calculators/retirement-planning
Authorization: Bearer <your API key>
Content-Type: application/json

API keys are issued from the FinCalc console by your institution's administrator.
