Create and Update Airtable records using Coinmarketcap API

Hello AirTable Team!
This may a simple ‘request’ to some of you. Here’s my ask…

What’s the best way to use the API from Most Trusted Cryptocurrency Market Data API | CoinMarketCap to

1. Get the data (list of all cryptocurrencies) - initial

2. Update the data (list of all cryptocurrencies) and append new crypto currencies to the list

3. I have my Coinmarketcap API key to get the free data

4. Not sure if I should use scripting or pay for DataFetcher account

Hoping someone can help

Thanks in advance,
Paul
