Get Token Prices

Get the price of a token from a variety of sources

In your webapp, you may want to show the current price of a token in the ecosystem or other ecosystems. Here are a few ways to get these prices to display. These should NOT be used for logic. If you wish to use token prices for logic, you will need to use an Oracle from multiple sources.

Coingecko

Coingecko is the most popular source for Crypto price feeds. It is free to use, and allows 1 query per 6 seconds by default. This should only be used for decoration, and no logic should be built off of it.

Python

        if len(api_key) > 0:
            self.cg = CoinGeckoAPI(api_key=api_key)
        else:
