Calculating Insurance Premium without place bet.

The getInsurancePremium method calculates the insurance premium for a bet based on the provided parameters. This function can be used independently without placing a bet. It determines whether the bet is a Single or Combo type and passes the appropriate data to the kohin.getInsurancePremium method. The result includes the calculated premium, which is processed and displayed accordingly.

For a Combo bet, set betType as "Combo", while for a Single bet, set betType as "Single". These distinctions allow the method to accurately compute the insurance premium based on the bet type and its corresponding rules.

Usage​

import kohin from "./kohinInstance";

const isSingle = true; // Set true for a "Single" (Ordinar) bet or false for a "Combo" (Express) bet.

const singleData = {
  betAmount: 50,
  betType: "Single",
  conditionId: "100610060000000000640676650000000000000906565289",
  outcomeId: "29",
  odds: 2.22829,
};

const comboData = {
  betAmount: 50,
  betType: "Combo",
  numLegs: 2,
  odds: 3.39794,
};

const data = isSingle ? singleData : comboData;
const res = await kohin.getInsurancePremium(data);

if (res?.success) {
  const premium = Number(res.calculatedPremium) / 10 ** 6;
  console.log("Calculated Premium:", premium);
} else {
  console.error("Error calculating premium:", res?.error);
}
