user69157: I've been searching for an API that returns the logo/image for a cryptocurrency. API's like CoinCap.io and Bittrex don't return this information in the response. Is there any public API which provides the logo for a specific cryptocurrency?

user134922: New update, seems like CoinCap.io stores their logos here:
https://assets.coincap.io/assets/icons/{}@2x.png
Just replace the parentheses above with the symbol of the cryptocurrency you are looking for. Example:
https://assets.coincap.io/assets/icons/btc@2x.png
The symbol can be found using the CoinCap.io API
https://api.coincap.io/v2/assets/bitcoin

Happy coding!

user78340: No particular API, but a solution how to get all logos from Coinmarketcap with the correct IDs can be found here: https://github.com/giekaton/cryptocurrency-logos

user63569: You can use their css class
http://coincap.io/css/spritesheet.css?v=1_6_1
attach it in your html file and call it like that for bitcoin logo:
<span class="sprite sprite-bitcoin small_coin_logo"></span>

But you have to contact them for copyright measures.
