Where can I find a free SPARQL endpoint with all GoodRelations data from the Web?
There is currently no "Google-like" RDF repository that offers you free access to the whole Web via a convenient SPARQL endpoint.

Some public SPARQL endpoints offer a moderate amount of such data, see


 * http://wiki.goodrelations-vocabulary.org/Public_endpoints

If this does not meet the needs for your application, you will have to crawl and cleanse the data yourself, e.g. from


 * http://wiki.goodrelations-vocabulary.org/Datasets

Crawling, cleansing, and consolidating structured data at Web scale is a non-trivial task, so do not expect someone else to do it for you for free. It may be a good business idea to offer such a service.
