My solution is save the page https://api.coinmarketcap.com/v1/ticker/?limit=100 or https://api.coinmarketcap.com/v1/ticker/?limit=1000 or whatever number you need to local computer file, plain text file, after that then read from the local computer file, and you can have as many queries as you need (as I estimated a normal use that updates prices several times a day and has some hundreds cryptocurrencies will have up to ~1 million requests queries a day, you think what the sever will do to you.).
