In this repo you can find the source code for the API and checking code that the Green Web Foundation servers use to check the power a domain uses.
Following Simon Brown's C4 model this repo includes the API server code in apps/api, along with the green check worker code in packages/greencheck.
Apps - API Server at api.thegreenwebfoundation.org
In /apps/api is the code served to you when you visit http://api.thegreenwebfoundation.org.
When requests come in, symfony accepts and validates the request, and creates a job for enqeueue to service with a worker.
See the project readme for further installation and deployment instructions.
In packages/greencheck is the library used for carrying out checks against the Green Web Foundation Database. Workers take jobs in a RabbitMQ queue, and call the greencheck code to return the result quickly, before passing the result, RPC-style to the original calling code in symfony API server.
In packages/publicsuffix is a library provides helpers for retrieving the public suffix of a domain name based on the Mozilla Public Suffix list. Used by the API Server.
