How to convert INR to wei_Eth : Reference Remix Fund Me.

[thelastdemon1337]

Hello,

I'm trying to take user input in terms of INR and convert to eth in wei for further transactions. Any idea how to implement this?
Any possible approach including any free API would be helpful. Thanks.

Use an API: You can use an external API to get the current ETH/INR exchange rate and then use it to convert user input in INR to ETH in wei. Some popular APIs for this purpose include CoinGecko, CryptoCompare, and CoinMarketCap. Here's an example of how you can use the CoinGecko API in JavaScript:

const axios = require('axios');

// Get the current ETH/INR exchange rate from CoinGecko
async function getEthInrRate() {
  const response = await axios.get('https://api.coingecko.com/api/v3/simple/price?ids=ethereum&vs_currencies=inr');
  return response.data.ethereum.inr;
}

// Convert INR to ETH in wei using the current exchange rate
async function convertInrToEthInWei(amountInInr) {
  const ethInrRate = await getEthInrRate();
  const amountInEth = amountInInr / ethInrRate;
  const amountInWei = amountInEth * 1e18;
  return amountInWei;
}

// Example usage:
convertInrToEthInWei(1000).then(amountInWei => console.log(amountInWei));
