Crypto Marketdata Cloud Function

This is a repository of a cloud function to proxy requests to CoinGecko with caching and rate limits, for use in Google Sheets, etc. This prevents your requests from being blocked by the CoinGecko's CDN rate limits. This function code makes requests to the v3 API to obtain market data for all coin, but you can change the URL in the code for your use case.
