Wrong request URL

[gnattily]

When using this module any request will return an error 404

Going to the URL http://coincap.io/coins/ (Generated from coincap.get_all_coins()) on a browser, it also returns a 404 error.

Here is something I think might help with this: https://docs.coincap.io/#9d1f0874-aa46-420c-9091-8bf9859c0743
