Developers can retrieve metadata about an algorithm from an HTTP endpoint.
The Algorithmia platform has an endpoint that you can use to get information about algorithms. It's a JSON response when you call a URL that includes "webapi" and then the path to the algorithm which includes the username or organization who has published the algorithm and the name of the algorithm.
Example: https://algorithmia.com/webapi/algorithms/deeplearning/ColorfulImageColorization
