- Auth: HTTP bearer

Calculate capital gains and tax on a property sale (our Capital Gains Calculator): indexed cost via the CII table, long-term (held over 2 years) vs short-term, and for long-term BOTH regimes compared (20% with indexation vs 12.5% without indexation, post July 2024 rules). For property bought before 1 April 2001, the fair market value as on 1.4.2001 replaces the purchase price (ask the user for it). Optional improvement/development costs with their years are indexed too. Dates must be YYYY-MM-DD. Free.

## Request body

  - `purchase_date` string, required: YYYY-MM-DD
  - `purchase_amount` number, required
  - `sale_date` string, required: YYYY-MM-DD
