Sorry, I linked to the wrong CoinGecko API reference. That one was for the Pro API. The Public API is here: https://docs.coingecko.com/v3.0.1/reference/simple-price
Coinbase doesn’t require authentication: https://docs.cloud.coinbase.com/sign-in-with-coinbase/docs/api-prices#get-spot-price
CoinGecko also: https://docs.coingecko.com/reference/simple-price
CoinGecko seems to rate limit more aggressively than Coinbase.

Perfect thanks Terry I'll check it!!
