You want to use a http client. There are a number of them, but hackney is a popular one. You can also search Hex for other Erlang http clients.

As well as an http client, you may also want a package to parse the results. This depends on whether your getting JSON or HTML back. For HTML, you should probably use XPATH. For JSON, use a library like jsx.
